The probability of having no girls in a family of 5 children, when each child is equally likely to be a boy or a girl, is $(\frac{1}{2})^5 = 0.03125$. This is because each child being a boy (the opposite event of having a girl) has a probability of $\frac{1}{2}$, and for 5 children, these probabilities are multiplied together.
