Past records indicate that the probability of online retail orders that turn out to be fraudulent is 0.07. Suppose that, on a given day, 18 online retail orders are placed. Assume that the number of online retail orders that turn out to be fraudulent is distributed as a binomial random variable. Complete parts (a) through (d) below. The mean number of online retail orders that turn out to be fraudulent is 1.2600 (Type an integer or a decimal. Round to four decimal places as needed.) The standard deviation of the number of fraudulent retail orders is 0.2708 (Type an integer or a decimal. Round to three decimal places as needed.) b. What is the probability that zero online retail orders will turn out to be fraudulent? 0.3669 (Type an integer or a decimal. Round to four decimal places as needed.) c. What is the probability that one online retail order will turn out to be fraudulent? (Type an integer or a decimal. Round to four decimal places as needed.) d. What is the probability that two or more online retail orders will turn out to be fraudulent? (Type an integer or a decimal. Round to four decimal places as needed.)
