A shipment of 9 television sets contains 2 black-and-white sets and 6 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?  Choose the most appropriate option
A) 1/7	B) 1/4	C) 5/14	D) 11/28	E) 7/12
I get 7/12, 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(6,2)/C(9/2)=21/36=7/12   7/12
