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 five marri women are having coffee together one morning. Find the following probabilities. (a) All of them dislike their mother-in-law (b) None of them dislike their mother-in-law. (c) At least three of them dislike their mother-in-law (d) No more than two of them dislike their mother-in-law. Step 1 (a) All of them dislike their mother-in-law A binomial experiment has a fixed number of independent trials and only two possible outcomes. R the binomial distribution with parameters n, p, r successes in a sequence of n trials, each of which yields success with probability p. ecall that and r gives the probability distribution of the number of Since there are 5 women having coffee together, the number of trials is fixed at 5. Whether or not one woman likes her mother-in-law will not influence whether or not another woman does, so the trials are doesn't. So, this scenario is a binomial experiment with n 5 trials. Here we will let a "success" be a woman disliking her mother-in-law. We are given that the probability that a Finally, there are two possible outcomes: that a woman likes her mother-in-law, or she woman does not like her mother-in-law is 85%, so p We are interested in the probability that all five women dislike their mother-in-law. Therefore, we want to find the probability of five successes, or Pr- [Submit ] [Skip (you cannotcomebacklExplanation / Answer
BINOMIAL PROBABILITY PROBLEM
MOTHER IS 85%
so p=0.85
Solutionb:
we are interested in
we want to find P(r=5)
