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.

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
The content structure consists of a homework help request in statistics, specifically about the distribution of boys and girls in families with three children, followed by an answer that provides the possible values of X (number of boys minus the number of girls) and the probability distribution for these values.
