7 action, 6 comedies, 8 dramas and 5 science fiction. So our sample space or possible outcomes is 7+6+8+5, or 26.
one thing to note is that AND means multiplication.
P(comedy) will be 6/26, favorable outimes over possible outcomes, and then we put it back, because we're putting it back in the box, the sample space is again 26, therefore P(drama) is 8/26, and then we multiply both.
