Question

Probability of four sons to a couple is

• A. 1/4
• B. 1/8
• C. 1/16
• D. 1/32

Answer 1

Answer: (C)

1/16

There are two possibilities to a couple for their child, that is either son or daughter. Probability of having either sex is 1/2. The probability for each child is independent of each other. Hence, the probability of four sons to a couple is (1/2)${}^n$, where n is the number of children.

Probability of four sons = 1/2 * 1/2 * 1/2 * 1/2 = 1/16.

Hence, the correct answer is option C.
