A survey of cross-border money transfers found that in 38% cases, the beneficiary account has suffered double charging, in contradiction to European Union rules. You randomly select 200 crossborder money transfers. Find the probability that the number who have encountered double charging at the beneficiary account is

(a) exactly 80,

(b) at least 80, and

(c) fewer than 80.

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
