There are 20 children in the cast of a class play, and 8 of the children are boys.  Of the boys, 5 have a speaking part in the play, and of the girls, 7 do not have a speaking part in the play.  If a child from the cast of the play is chosen at random, what is the probability that the child has a speaking part?

20 children total       8 boys       soooo    12 girls

5 boys with speaking parts         5 girls with speaking parts

  10 total speaking parts   out of 20    

10/20 = 1/2 probability
