n!
n k
to solve the combination.
How many ways can you
choose steak, fish, or chicken if you
can only choose two meats?

Answer 1

Answer:

3 ways.

Step-by-step explanation:

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

2 meats from a set of 3(steak, fish or chicken). So

$C_{3,2} = \frac{3!}{2!1!} = 3$

3 ways.
