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 :)

  • statistics -

    Number of children = 3
    Possible number of boys = {0,1,2,3}
    X=number of boys - number of girls

    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
