    Answer:

    66045 ways

    Step-by-step explanation: There are actually total of 37 student, and total of 4 jobs. But if the jobs are to be done by only one person each, then we are selecting 4 students.

    So the number of ways of selecting 4 out of 37 using combination is

    =37C4

    =37!/(37-4)!(4!)

    =37!/33!4!

    =66045
