A shipment of 8 television sets contains 2 black-and-white sets and 6color 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?
A. 1/7 B. ¼ C. 5/14 D. 11/28 E. 13/26

Pl. solve the prob. ques...could u find ur ans in any one of the choices? I'm once again puzzled...are there misprinting in GMAT sets? are their OA correct....if not...then sometime it may sack ur confidence...pl. express ur views apart from solving this good prob. thanks;
Hi friends ! Just started GMAT prep. Hope to share thoughts, experience, joy and agony of GMAT prep journey.

Regards; neeraj

I get the ans as 13/28, sometimes the OA may be misprinted/wrong
& sometimes ur soln/approach may be wrong

btw what is the OA here.
Regards
Samir
