Expert Answer
The probability of husband selection ,P(H) = 1/7 probability of selecting wife P(W) = 1/5
The probability of not selecting the husband is P(H') = 8/7
The probability of not selecting the wife P(W')= 4/5
(i) Probability of both of them will be selected =P(H)P(W)= 1/35
(ii) Probability of only one of them will be selected =P(H)P(W')+ P(H')P(W) = 8/35+4/35 = 12/35
(iii) Probability of none of them selected = P(H')P(W') = 32/35
