@chandrakant.k@vbhvgupta@DeAdLyThere are 3 white balls and 4 black balls in a bag, and a set S = {0, 1}. Now one ball is chosen from the bag and if it's white then the set S remains the same and if the ball chosen is black then the element '1' is replaced by '–1' in the set S. After choosing one ball and fixing the set S, three numbers α, β, γ (not necessarily distinct) are chosen from the set S. Then what is probability of having real and finite number of solutions of the equationxα + xβ + γ = 0OPTIONS1) 2) 3) 4) None of the above

looks like the question is asking for something like
6c1/12c1 [1 woman]+5c1/12c1 [1 man without desrt]=6/12+5/12=11/12..!!!
@happy3475 Right, now its clear as you highlighted it. Its just the sentence, that it can be a woman (with or without desert) OR A MAN (without Dessert only)
