A shipment of 8 television sets contains 2 black-and-white sets and 7 color sets. If 2 television sets are to be chosen at random from this shipment, what is the probability that at least 1 of the 2 sets chosen will be a black-and-white set? Select the correct option:
A) 1/7 B) 1/4 C) 5/14 D) 11/28 E) 13/28
I get 1/4, which is not in the answer choices.   the probability of getting at least one b/w TV is 1-(the probability of getting 2 color TVs)   1-C(7,2)/C(8/2)=7/28=1/4   1/4
