Critical Thinking Consider a binomial distribution with n 510 trials and the probability of success on a single trial p 5 0.85.

(a) Is the distribution skewed left, skewed right, or symmetric?

(b) Compute the expected number of successes in 10 trials.

(c) Given the high probability of success p on a single trial, would you expect P(r # 3) to be very high or very low? Explain.

(d) Given the high probability of success p on a single trial, would you expect P(r $ 8) to be very high or very low? Explain.
