What is the probability of drawing two red marbles, if you don't replace the marble after you draw the first one? 1/51 1/6 1/36 1/54 The school play has two leading roles. The play's director decides to choose the leading actors by drawing two names from a hat that contains the names of four students who want the lead parts.
