Question

Charles has eight different winter scarves, and he wears three at a time. How many different ways can Charles wear three scarves? 6,720 56 112 336

Answer 1

Ans= 6720 ways

Explanation:

From Combination rule from Permutation and Combination, nCr

We use 8^C3 or 8C3,

8x7x6x5x4x3x2x1

-------------------------- =6,720

3x2x1

or

8x7x6x5x4x3! /3!, here the 3! cancels each other out, and we're left with 8x7x6x5x4, which equals 6720.
