Question

For this question, use a Binomial Probability Distribution. Assume all conditions are met.

According to data from the U.S. Social Survey, the probability that an adult was never in a museum is 15%. You may safely assume that one randomly selected adult having never been in a museum does not change the chances of another adult having never been in a museum.

(a) If 10 adults are randomly surveyed, what is the probability that 6 of them have never been in a museum? Type your answer as a proportion (not a percentage) rounded to the third decimal place. ____________

(b) If 10 adults are randomly surveyed, what is the probability that 2 or fewer of them have never been in a museum? Type your answer as a proportion (not a percentage) rounded to the third decimal place. ____________

(c) What is the expected value (mean) of the number of adults who have never been in a museum out of the 10 adults surveyed? Type your answer as a value rounded to the first decimal place. _______________
