There are 10 stamps from which two stamps will be selected. We have five stamps which are the same as five of the stamps which could be selected. What is the probability that the two stamps selected will be different from the stamps that we have? Select:  A) 7/17  B) 5/12  C) 4/11  D) 3/10  E) 2/9
P(first stamp is different) = 5/10   P(second stamp is different) = 4/9   P(both stamps are different) = 5/10*4/9 = 2/9   The answer is 2/9.
