A bag contains 9 tiles, each with a different number from 1 to 9. You choose a tile without looking, put it aside, choose a seco

Ksenya-84 [330]

Using the combination formula, it is found that there are 84 ways to choose the three tiles.

The order in which the tiles are chosen is not important, hence the <em>combination formula</em> is used to solve this question.

<h3>What is the combination formula?</h3>

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

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

In this problem, three tiles are chosen from a set of nine, hence:

$C_{9,3} = \frac{9!}{3!6!} = 84$

There are 84 ways to choose the three tiles.
