Answer: Hence, the probability of having no girls is 0.0313.

Step-by-step explanation:

Since we have given that

Number of children a family has = 5

Number of outcomes would be 2^5=32

Probability of having a girl = \dfrac{1}{2}=0.5

We need to find the probability of having no girls.

P(no girls ) = P( all boys )

So, it becomes,

P(all\ boys)=(0.5)^5=0.03125\approx 0.0313

Hence, the probability of having no girls is 0.0313.
