  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
