1/5 There are six possible pairings of the two balls withdrawn, Yellow+Yellow Yellow+Green Green+Yellow Yellow+Black Black+Yellow Green+Black. We know the Green + Black combination has not been drawn. This leaves five possible combinations remaining. Therefore the chances tbowl the Yellow + Yellow pairing has been drawn are 1 in 5. Many people cannot accept tbowl the solution is not 1 in 3, and of course it would be, if the balls had been drawn out separately and the color of the first ball announced as Yellow before the second had been drawn out. However, as both balls had been drawn together, and then the color of one of the balls announced, then the above solution, 1 in 5, must be the correct one.
