Asked by Ariana
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
