Solution

## According to the given parametersTotal numbers of families given in the question $1500$ We want to find out the probability of selecting $2$ girlsNumber of girls in a family$2$$1$$0$Number of families$475$$814$$211$Numbers of families having $2$ girls $=475$Probability of choose $2$ girls $=$ Numbers of families having $2$ girls $/$Total numbers of families $=\frac{475}{1500}$ $=\frac{19}{60}$ Hence$,$ Probability of choose $2$ girls is $\frac{19}{60}$
