5. If 4 married couples are arranged in a row, find the probability that no husband sits next to his wife. Hint. Let Ak-"kth couple sits together", k = 1.2.3.4. Apply inclusion/exclusion principle and think about the book arrangement on the shelf: P (at least one couple sits together) i-1 i<j<k For instance with i < j. AiAj -"the ith couple and the jth couple go together, the remaining 4 people are arranged in any order".

In a survey in a certain year of married couples with earnings, 93% of all husbands were employed. Of all employed husbands, 73% of their wives were also employed. Noting that either the husband or wife in a couple with earnings had to be employed, find the probability that the husband of an employed woman was also employed. (Round your answer to four decimal places.)
