A bag contains 2 gold coins and 5 silver coins. A number cube has the numbers 1 through 6 on its faces. What is the probability of drawing a silver coin from the bag and rolling an even number on the number cube? A.5/43 B.5/14 C.5/9 D.2/3

OpenStudy (campbell_st):

P(silver) = 5/7 P(even) = 1/2 P(silver, even) = 5/7 * 1/2
