Question

Calculate the following combinations

Answer 1

Answer:

$_3 C_2 =\frac{3}{2}$

$_3 C_3$ Is undefinded.

Step-by-step explanation:

Given the equations.

$_3 C_2=\frac{3}{(3-2)2}$

$_3 C_3 =\frac{3}{(3-3)3}$

Distribute the denominator.

$_3 C_2 =\frac{3}{(6-4)}$

$_3C_2 = \frac{3}{(9-9)}$

Simplify the denominator.

$_3 C_2 = \frac{3}{2}$

$_3 C _3 = \frac{3}{0}$ this is undefined because you're not able to divide by 0.
