Kimberly has seven colors of lanyards. she uses three different colors to make a key chain. how many different combinations can she choose?

Respuesta :

The number of different combinations can she choose is; 210.

What is the permutation?

We are told that;

Number of colors of Lanyards she has = 7

Number she wants to use to make a key chain = 3 colours

Thus, number of different combinations can she choose is gotten through permutation formula;

P(n, r) = n!/(n - r)!

P(7, 3) = 7!/(7 - 3)!

P(7, 3) = 210

Thus, the number of different combinations can she choose is 210.
