The students in your class with three children in their families are asked to state the number of boys in the family. What are the possible numbers? If X is the number of boys minus the number of girls in each of these families, state all the possible values of X. Make a table of probability distribution.

Step by step please?

Thanks in advance :)

Number of children = 3

Possible number of boys = {0,1,2,3}

X=number of boys - number of girls

={-3,-1,1,3}

P(X)= probability of event X.

b g X P(X)

0 3 -3 1/8

1 2 -1 3/8

2 1 1 3/8

3 0 3 1/8
