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.
