Sociology: Mother-in-Law Sociologists say that 90% of married women claim that their husband’s mother is the biggest bone of contention in their marriages (sex and money are lower-rated areas of contention). (See the source in Problem 18.) Suppose that six married women are having coffee together one morning. What is the probability that

(a) all of them dislike their mother-in-law?

(b) none of them dislike their mother-in-law?

(c) at least four of them dislike their mother-in-law?

(d) no more than three of them dislike their mother-in-law?
