Firstly, solve 38C15.
Then solve 42C12.
Compare your answers.
The goal here is to see if 38C15 = 42C12.
Here is the formula:
nCr = n!/(r!(n - r)!
Go for it.
Answer:
6/8
9/12
12/16
Step-by-step explanation:
Its is 74 because you add all of them then subtract it from the total which in your case is 360
