Best answer 2 votes 2 votes Husband can be selected and not wife, wife can be selected and not husband and both can also be selected so (1/7)(1/5) + (1/7)(1 - 1/5) + (1/5)(1 - 1/7) = 11/35 (Option B) Or simply 1-P(no one gets selected kf the couple) =1- (4/5)(6/7) = 11/35 Rahul Jain25 answered Mar 2, 2017 • selected Mar 2, 2017 by Sanjay Sharma Rahul Jain25 comment Share Follow See all 3 Comments See all 3 3 Comments reply Akriti sood commented Mar 2, 2017 reply Follow Share but question asks for anyone of them..not that probaility of atleast 1 0 votes 0 votes Rahul Jain25 commented Mar 2, 2017 reply Follow Share Well after your comment I too got confused, but this link will help.
