A die is thrown once. What is the probability of getting a prime number?
सही उत्तर: ख) 1/2
The primes on a die are 2, 3 and 5, so P = 3/6 = 1/2. Note that 1 is not a prime number.

A bag contains 5 red and 3 blue balls. Two balls are drawn at random without replacement. What is the probability that both are red?
सही उत्तर: क) 5/14
P = ⁵C₂/⁸C₂ = 10/28 = 5/14. 25/64 would apply only if the first ball were put back.

A card is drawn at random from a well-shuffled deck of 52 cards. What is the probability that it is a king?

Two fair dice are thrown. What is the probability that the sum of the numbers is 7?
सही उत्तर: ख) 1/6
There are 6 favourable pairs (1,6), (2,5), (3,4), (4,3), (5,2) and (6,1) out of 36 outcomes, so P = 6/36 = 1/6. Sum 7 is the most likely total.

Two coins are tossed together. What is the probability of getting at least one head?
सही उत्तर: ख) 3/4
The outcomes are HH, HT, TH and TT. Only TT has no head, so P = 1 − 1/4 = 3/4.

How many diagonals does a hexagon have?
सही उत्तर: ख) 9
Number of diagonals = n(n − 3)/2 = 6 × 3/2 = 9. 15 is ⁶C₂, which also counts the 6 sides.

-
At a meeting, each of 10 people shakes hands with every other person exactly once. How many handshakes take place?
सही उत्तर: ख) 45
Number of handshakes = ¹⁰C₂ = 10 × 9/2 = 45. 90 counts each handshake twice.

A committee of 2 men and 2 women is to be formed from 5 men and 4 women. In how many ways can this be done?
सही उत्तर: क) 60
⁵C₂ × ⁴C₂ = 10 × 6 = 60. 126 is ⁹C₄, which ignores the condition on men and women.

-
In how many ways can 3 students be selected from a group of 8?
सही उत्तर: क) 56
⁸C₃ = 8 × 7 × 6/(3 × 2 × 1) = 56. 336 is ⁸P₃, which counts ordered arrangements instead of selections.
