Question

Compute the following 8c8

a.
16
b.
0
c.
64
d.
1

Answer 1

d. 1

Explanation:

To solve for the combination, you just need to remember the formula:

`_(n)C_(r)=(n!)/(r!(n-r)!)`

So you just need to fill in the formula:

`_(n)C_(r)=(n!)/(r!(n-r)!)`

`_(8)C_(8)=(8!)/(8!(8-8)!)`

`_(8)C_(8)=(8!)/(8!(0)!)`

`_(8)C_(8)=(8!)/(8!)`

`_(8)C_(8)=1`
