CAT Exam Important Topic: Strategy to Prepare Probability Questions For CAT Exam, Permutation and Combination
Important Concept/Formula Used in CAT Probability Practice Questions
CAT Probability or Chance:
Probability is a quantitative measure of the chance of occurrence of a particular event.
PE=n(E)/n(S), n(E) = no of favourable events; n(S) = Sample Space.
Random Experiment probability problems
If all the possible outcomes of an experiment are known but the exact output cannot be predicted in advance.
Examples
(i) Tossing of a fair coin (Total Outcome 2)
(ii) Dice probability questions
Throwing an unbiased die (Total Outcome 6)
(iii) Cards game probability questions
Drawing a card from a pack of shuffled cards
A pack or deck of playing cards has 52 cards which are divided into four categories as given below
a. Spades (♠)
b. Clubs (♣)
c. Hearts (♥)
d. Diamonds (♦)
[13 Cards: 9 Number cards, 1 Ace, 1 Jack, 1 Queen and 1 King] in each type
Sample Space: Sample Space is the set of all possible outcomes of an experiment. It is denoted by S.
Event: Any subset of a Sample Space is an event.
Equally Likely Events: Events are said to be equally likely if there is no preference for a particular event over the other.
Examples
(i) When a coin is tossed, Head (H) or Tail is equally likely to occur.
Mutually Exclusive Events: if the occurrence of one of the events excludes the occurrence of the other
Example
(i) Tossing of a coin: either Head or Tail.
(iii) Rolling of a die: Either odd or even.
Independent Events: The occurrence or non-occurrence of one event does not influence the occurrence or non-occurrence of the other.
Exhaustive Event is the total number of all possible outcomes of an experiment.
Examples
(i) When a coin is tossed, we get either Head or Tail. Hence there are 2 exhaustive events.
Q1. Difficult aptitude questions on probability
A coin of radius 3 cm is randomly dropped on a square floor full of square-shaped tiles of 10 cm each. What is the probability that the coin will land completely within a tile? In other words, the coin should not cross the edge of any tile.[XAT 2018]
0.91
0.5
0.49
0.36
0.16
Solution: (E)
The radius of the coin is 3 cm. Since the coin should not cross the edge, the centre of the coin should at least be 3 cm away from the edge of the tile.
If we left 3 cm from all the edges, then the centre can lie in a square of 4 x 4.
So, Probability = Area of square 4 x4/ Area of tile
= 16/100 =0.16.
Q2. A die is thrown three times and the sum of the three numbers is found to be 15. The probability that the first throw was a four is [IPMAT 2019]
1/6
¼
1/5
1/10
solution: [C]
We can get sum 15 if
Case 1: 6, 6, 3
Total outcome = 3!/2! = 3
Favourable outcome (getting 4 at first throw) = 0
Case 2: 6, 5, 4
Total outcomes = 3! = 6
Favourable outcome (getting 4 at first throw) = 2 (4, 5, 6 or 4, 6, 5)
Case 3: 5, 5, 5
Total outcome = 1
Favourable outcome (getting 4 at first throw) = 0
Probability = 2/10 = 1/5.
Tricks and Tips of CAT permutations and combinations, probability
Learn Algebra of Events
(i) A ∪ B is the event that either A or B or Both occur. (i.e., at least one of A or B occurs)
(ii) A ∩ B is the event that both A and B occur
(iii) is the event that A does not occur
(iv) is the event that none of A and B occurs
P(S) = 1
0 ≤ P (E) ≤ 1
P(ϕ) = 0 (∵ Probability of occurrence of an impossible event = 0)
Let x outcomes be favourable to E and y outcomes are not favourable to E, then
Odds in favour of E are x:y, i.e.,x/y and
Odds against E are y:x, i.e.y/x
PE=x/x+y
PE'=y/x+y
Learn Conditional Probability.
Binomial Distribution:”
P (r successes in n trials) =
If n fair coins are tossed,
The Total number of outcomes in the sample space = 2n
The probability of getting exactly the r-number of heads when n coins are tossed =

CAT 2024 Syllabus Topic: Strategy to prepare “Data Sufficiency in LR (Part-1)” for CAT
CAT Exam: About Topic/ Formulas
While the genre of Data Sufficiency is unique, the structure is not – all Data Sufficiency questions are structured the same, with three key elements:
The question stem: may or may not contain important facts
The statements: always two statements
The answer choices: always the same.
Sample Question based on PYQs on Data Questions for CAT/ MBA Entrance Exam:
Q1. In a particular school, sixty students were athletes. Ten among them were also among the top academic performers. How many top academic performers were in the school?
I. Sixty per cent of the top academic performers were not athletes.
II. All the top academic performers were not necessarily athletes. [CAT 2007]
Statement I alone is sufficient to answer this question but statement II is not sufficient to answer this question.
Statement II alone is sufficient to answer this question but statement I is not sufficient to answer this question.
None is sufficient to answer this question.
Both statements together are sufficient to answer this question.
Solution: [A]
Statement I: 40% of top academic performers are athletes = 10.
Statement II: does not provide any relevant information.
So the answer is (1).
Tips and Tricks for CAT 2024
Ask yourself the following questions (starting with the statement (1):
Is the information in the statement (1) alone enough to answer the question?
Is the information in a statement (2) alone enough to answer the question?
Can an answer be given if with the information from statements (1) and (2) both?
A statement is sufficient when it guarantees exactly one (and only one) answer to the question.
You do not have sufficient information if more than one answer is possible
Do not solve the question after the moment you know the unique answer can be found thereafter.
If the answer from one statement alone and by combining both statements can be found out then the answer will be from one statement alone.
Stick to the basics.

Sample Questions:
Directions: Choose a similar word from the given options for highlighted phrase/word.
Q1. Public policy in regard to food in main economies around the world has not provided adequate incentive, and the response to emergencies like accidents is equally sad.
Acceleration
Surplus
Baiting
Encouragement
Ans: D
Explanation: The context of the sentence refers to Encouragement. Hence option D is correct.
Q2. We today can see a swing away from these stereotypes, or have they established a stranglehold on our perceptions.
Asphyxiation
Containment
Prohibiting entry
Overwhelming control
Ans: D
Explanation: Asphyxiation- it happens when someone is literally strangled. And here the context is different.
Containment: it cannot be established and hence can be eliminated.
It does not seem appropriate here.
Prohibiting entry is for physical context and not for abstract. Hence can be eliminated.
Overwhelming control is a perfect fit here. Hence option D is correct.
One needs to be careful about the context.
Every word in the English language has a lot of different meanings.
To learn synonyms one can create word families
Beautiful- Gorgeous, Dazzling, Splendid, Magnificent
Important- necessary, vital, critical, Indispensable
One can also take reference from root words.
One can learn synonyms by logically associating a word with a sentence or a situation.
One needs to carefully observe the sentence's meaning as a whole.
Another method is to eliminate the other options.
Practise more and more exercises.

On average, in the quantitative aptitude section of the CAT exam, you might expect to see around 2 to 4 questions related to probability. This is a rough estimate based on historical data up until 2024.
The student cannot join the postgraduate MA program directly in the second year of the MA after completing the MBA.
Universities generally expect students to begin the first year of a masters' program even though they had qualifications at the level of a bachelor's degree. The university's curriculum along with the courses are planned to give an in-depth knowledge of the subjects.
But you could opt for:
Postgraduate Studies:
Research Career: In case research interests you, then you can pursue a Ph.D. in your specific interest.
Specialized Master's Programs: Find any specific master's course that supports the career goal.
Professional Certifications:
Make a professional certification in CFA, CA, or FRM to enhance the professional skills and better opportunities in the career field.
Job Entry via MBA
After gaining an MBA from a renowned institution, it's possible to get entry into the corporate world where the diversity in the career field is assured.
In the end, it would depend on what you would like and what you are particularly interested in. It will be better if you take a suggestion from your academic advisor or career counselor.
Hello Pratik,
If your family income exceeds 8 LPA, it will affect your eligibility for the NC-OBC category under the CAT reservation rules. The NC-OBC category requires that the family income should be below 8 LPA to qualify. If you anticipate that your income will exceed this threshold, you should update your status and notify the CAT authorities .
Here's what you can do:
Email the CAT authorities
: Inform them about the potential change in your income status and request to be considered under the
General
category, if applicable. You should do this before the examination or any further processing, as your eligibility for the OBC category depends on the income criteria.
Documents and Proof
: Make sure you have a valid
OBC certificate
and any relevant documentation regarding your family income, in case they require verification. Also, be aware that if your income exceeds 8 LPA, you might need to apply under the
General
category, as the OBC-NC reservation is no longer applicable.
General Category Consideration : If your application is accepted as General, you will be evaluated based on the General category criteria, including cutoffs and ranking.
To summarize, notifying the CAT authorities is the correct approach to avoid discrepancies later, and if your income is above the threshold, you will be treated as a General candidate for the admissions process.

Hello,
Yes, you can also join IIMs two years after graduation, depending upon the justification in interviews and your performance in entrance exams. If you are not sure about CAT, try those other management exams less hard:
Common Management Admission Test: Easier than CAT; 4-5 months of continuous preparation will suffice.
MAT : Much easier and takes place thrice a year.
SNAP (Symbiosis National Aptitude Test): A bit easier than CAT, apt for Symbiosis Institutes.
Xavier Aptitude Test or XAT : Hence, easier than CAT but the unique decision-making section.
Use exams like CMAT and MAT as a challenge to be competitively prepared. This can be given about 4-5 months, along with a few rounds of mock tests and smart studying.
