Question

Probability of four son to a couple is:

• A. $\frac{1}{4}$
• B. $\frac{1}{8}$
• C. $\frac{1}{16}$
• D. $\frac{1}{32}$

Answer 1

The correct option is C $\frac{1}{16}$

The probability of a couple having a son is $\frac{1}{2}$.
So the probability of a couple having four sons is $\frac{1}{2}$ * $\frac{1}{2}$ * $\frac{1}{2}$ * $\frac{1}{2}$ or $\frac{1}{16}$.
