Question

A tutor gives John 5 assignments and asks him to complete 5. How many possible combinations? Pls answer ASAP

Answer 1

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`
