360 = 37.50x + 60
-60 on both sides
300 = 37.50x
/37.50 on both sides
8 = x

The expected number of female children in a family with three children is 1.5.
The correct option is B.
We have to determine
What is the expected number of female children in a family with three children?
<h3>Probability;</h3>
Probability is defined as the sum of all observations and the number of observations.
The expected value of female children= Probability of female children x Total number of children.
A child can be male or female, so there are 2 combinations, the favorable outcome is female.
The probability of female children = 1/2.
Therefore,
The expected number of female children in a family with three children is;
