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 [tex]2^5=32[/tex]
Probability of having a girl = [tex]\dfrac{1}{2}=0.5[/tex]
We need to find the probability of having no girls.
P(no girls ) = P( all boys )
So, it becomes,
[tex]P(all\ boys)=(0.5)^5=0.03125\approx 0.0313[/tex]
Hence, the probability of having no girls is 0.0313.
