Answer:

There is 1 possible combination

Explanation:

There are 5 assignments and they must be completed. 5. We want to find the number of combinations, then we use the formula of combinations.

nCr =(n!)/(r!(n-r)!)

Where n is the total number of objects and you choose r from them

Then

$n= 5\\\\r = 5$

5C5 =(5!)/(5!(5-5)!)

5C5 =(5!)/(5!(0)!)

5C5 =(5!)/(5!)

5C5 =1
