(a) Make a histogram of the probability distribution of r.
(b) What is the probability of getting 5 or more days when the surf is at least 6 feet?
(c) What is the probability of getting fewer than 3 days when the surf is at least 6 feet?
(d) What is the expected number of days when the surf will be at least 6 feet?
(e) What is the standard deviation of the r-probability distribution?
(f) Interpretation Can you be fairly confident that the surf will be at least 6 feet high on one of your days off? Explain.Distribution
