Construct the probability distribution for X. (c) (5 points) How much weight can you expect to gain by age 50?

Construct the probability distribution for X. (c) (5 points) How much weight can you expect to gain by age 50? (d) (5 points) Exercise and diet greatly influence these probabilities. Suppose with exercise and a proper diet the probability you will gain 10 pounds drops to 0.4, and the probability you will gain 30 pounds drops to 0.1. In this case, how much weight can you expect to gain? 4. A New York Times/CBS News poll found that 39% of Americans think the country is headed in the right direction. Suppose six people are randomly selected and the number of people who think the country is headed in the right direction is recorded. (a) (4 points) Explain why this is a binomial experiment. (b) (2 points) What is the random variable for this probability experiment?
