$50$ families with $2$ children were selected randomly and the following data were recorded:

Number of girls in a family	$0$	$1$	$2$
Number of families	$10$	$32$	$8$

If a family is chosen at random,compute the probability that it has: $(1)$ two girls,$(2)$ one girl,$(3)$ no girl.

The total number of families is $50$.
$(1)$ Probability of having $2$ girls:
Number of families with $2$ girls = $8$.
Probability = $\frac{8}{50} = 0.16$.
$(2)$ Probability of having $1$ girl:
Number of families with $1$ girl = $32$.
Probability = $\frac{32}{50} = 0.64$.
$(3)$ Probability of having no girl:
Number of families with $0$ girls = $10$.
Probability = $\frac{10}{50} = 0.20$.
