A bag of coins contains 12 pennies, 7 nickels, 4 dimes, and 2 quarters. once a coin is drawn from a bag it is not replaced. If 2 coins are drawn at random, what is the probaility of drawing a quarter first and then a penny?
P(quarter first from 25 coins AND penny second from 24 coins)

P(quarter first from 25 coins) × P(penny second from 24 coins)

                            2     12
                           --- × ----
                           25     24

                            2     1
                           --- × ---
                           25     2
                          

                               1
                              ---
                              25
