Two cards are drawn one after the other from a pack of 52, the first being put back before the second is drawn. What is the probability that both are aces?
सही उत्तर: ग) 1/169
With replacement the draws are independent: (4/52) × (4/52) = (1/13)² = 1/169.

The letters of the word NEPAL are arranged at random. What is the probability that the two vowels come together?
सही उत्तर: क) 2/5
Favourable arrangements = 4! × 2! = 48 out of 5! = 120, so the probability = 48/120 = 2/5.

How many subsets of {1, 2, 3, ..., 10} contain the number 1 but not the number 2?
सही उत्तर: क) 256
1 must be in and 2 must be out; each of the other 8 numbers is free to be in or out: 2⁸ = 256.

In how many arrangements of the letters of the word MATH is M not the first letter?
सही उत्तर: क) 18
Total arrangements 4! = 24; those beginning with M are 3! = 6; so 24 − 6 = 18.

How many five-letter words (all letters different, meaning ignored) containing 2 vowels and 3 consonants can be formed from 5 vowels and 7 consonants?
सही उत्तर: क) 42,000
Choose the letters in ⁵C₂ × ⁷C₃ = 10 × 35 = 350 ways and arrange the 5 chosen letters in 5! = 120 ways: 350 × 120 = 42,000.

How many five-digit numbers divisible by 4 can be formed using each of the digits 1, 2, 3, 4 and 5 exactly once?
सही उत्तर: ख) 24
The last two digits must form a multiple of 4: 12, 24, 32 or 52 (4 choices); the other three digits can be arranged in 3! = 6 ways, giving 24.

In how many ways can three different numbers be chosen from 1, 2, ..., 20 so that they form an arithmetic progression (in some order)?
सही उत्तर: ख) 90
For common difference d the smallest term can be 1 to 20 − 2d, giving (20 − 2d) choices for d = 1, ..., 9: 18 + 16 + ... + 2 = 90.

All arrangements of the letters of the word SURE are listed in dictionary order. In which position does SURE appear?

In an arithmetic progression the 7th term is 12 and the 12th term is 7. What is the 19th term?
सही उत्तर: घ) 0
Common difference = (7 − 12)/(12 − 7) = −1, so the 19th term = 7 + 7 × (−1) = 0.
