A test of 10 different types of candy are being tested. If a person is given 6 of the candies to taste how many combinations are

ASHA 777 [7]

There are 210 different possible combinations

<h3>How to determine the number of possible combinations?</h3>

The given parameters are:

Types of candy, n = 10
Candies to taste, r = 6

The number of possible combinations is calculated using:

Combination = nCr

This gives

Combination = 10C6

Apply the combination formula

Combination = (10!)/((10 - 6)!6!)

Evaluate

Combination = 210

Hence, there are 210 different possible combinations
