john, Juan, Antonio, and Eve are billing clerks in an office. Of the number of erroneous billings prepared, 40% were done by Mark, 20% were done by Bill, 10% were done by Linda, and the rest were done by Joan. Given seven erroneous billings, what is the approximate probability that two were prepared by Mark, one by Bill, one by Linda, and three by Joan? Determine if the answer is (A) 0.036 (B) 0.047 (C) 0.058 (D) 0.082
