Question
Past records indicate that the probability of online retail orders that turn out to be fraudulent is 0.08. 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 1.4400.
(Type an integer or a decimal. Round to four decimal places as needed,)
Instructor tip
The standard deviation of the number of fraudulent retail orders is 1.151
(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?
Use =BINOM.DIST function in Excel for parts b), c), and d).
0.2229 (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?
0.3489 (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.)
