a) P(wife is watching television) =P(wife is watching television | husband is watching television) * P(husband is watching television) + P(wife is watching television | husband is not watching television) * P(husband is not watching television)

= 0.6 * 0.9 + 0.2 * (1 - 0.9) = 0.56

P(husband is watching television | the wife is watching television)

= P(wife is watching television | husband is watching television) * P(wife is watching television)/P(husband is watching television)

= (0.6 * 0.56)/0.9 = 0.3733
