Two cards are drawn together from a well-shuffled pack of 52. What is the probability that at least one of them is an ace?
सही उत्तर: क) 33/221
P(no ace) = C(48,2)/C(52,2) = 1,128/1,326 = 188/221; so 1 − 188/221 = 33/221.

Two different numbers are chosen at random from 1 to 10. What is the probability that their sum is even?
सही उत्तर: ख) 4/9
Sum is even when both are odd or both even: 2 × C(5,2) = 20 of C(10,2) = 45, i.e. 4/9.

A positive divisor of 60 is chosen at random. What is the probability that it is even?
सही उत्तर: क) 2/3
60 has 12 divisors; the even ones are 2, 4, 6, 10, 12, 20, 30, 60 (8), so 8/12 = 2/3.

Three vertices of a regular hexagon are chosen at random. What is the probability that they form an equilateral triangle?
सही उत्तर: ग) 1/10
C(6,3) = 20 triangles; only 2 (alternate vertices) are equilateral: 2/20 = 1/10.

A two-digit number is chosen at random. What is the probability that its two digits are different?
सही उत्तर: घ) 9/10
Two-digit numbers: 90; with equal digits: 9 (11, 22, …, 99); so 81/90 = 9/10.

How many triangles can be formed using the vertices of a regular decagon (10-sided polygon) as corners so that no side of the triangle is a side of the decagon?
सही उत्तर: ख) 50
Total C(10,3) = 120; triangles sharing two sides = 10; sharing exactly one side = 10 × 6 = 60; 120 − 70 = 50.
