Suppose we want to choose 7 colors, without replacement, from 9 distinct colors
If the order of the choices does not matter, how many ways can this be done?

Respuesta :

MrRoyal

The number of ways to choose the colors is 36

How to determine the number of ways?

The given parameters are:

Colors = 9

Colors to choose = 7

Since order does not matter, then it is combination

This is calculated using:

[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]

This gives

[tex]^nC_r = \frac{9!}{7!2!}[/tex]

Evaluate

[tex]^nC_r = 36[/tex]

Hence, the number of ways is 36
