CLT Company has three sales departments. Department A processes about 50% of CLT sales, Department B about
30%, and Department C about 20%. In the past, Departments A, B, and C had error rates of about 2%, 5%, and 2.5%,
respectively. A random audit of the sales records yields a recording error of sufficient magnitude to distort the
company results. The probability that Department A is responsible for this error is
A.
