Answer: -512
Step-by-step explanation:
(18-26) = -8
(-8)^3 = (-8)*(-8)*(-8) = -512
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.
Due to the nature of spheres, they are all similar to each other.
1 1/2 or 3/2 because there is 4 more than 8 which is a half.
