Question

Sociologists say that 85% 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). Suppose that eight married women are having coffee together one morning. Find the following probabilities. (For each answer, enter a number. Round your answers to three decimal places.)

(a) All of them dislike their mother-in-law.

(b) None of them dislike their mother-in-law.

(c) At least six of them dislike their mother-in-law. (d) No more than five of them dislike their mother-in-law.

Answer 1

The probability that a married woman dislike her mother-in-law is 85% =0.85 =p, say

Hence, the probability that a married woman does not dislike her mother in law is 1- p = 0.15

The required probability calculations are shown in the attachments below.
