A survey of German adults found that 73% of customers who shop online pay through PayPal. You randomly select 150 German adults who shop online. Find the probability that the number who pay through PayPal is

(a) at least 100,

(b) fewer than 100, and

(c) more than 120.

Determine whether you can use a normal distribution to approximate the binomial distribution. If you can, use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot, explain why and use a binomial distribution to find the indicated probabilities. Identify any unusual events. Explain
