Demarcus Waters · Answer 1

It is indeed justifiable that the operation involved in this task is combination because the arrangement of the assignments are not important. The combination may be solved directly from a scientific calculator using the function,

nCr

where in this item the value of n is 8 and that of r is 3. Substituting and solving the combination,

8C3 = 56

Therefore, there are exactly 56 combinations possible.
