Question

1. Ten school children are asked to stand in a line to wait for ice cream cones.

Answer 1

Answer:

There are 3628800 possible number of arrangements

Explanation:

Given

Number of children = 10

Required

Possible number of arrangements

From the question, we understand that the order of arrangement matters;

So; to solve this, we make use of the following formula

$n! = n * (n-1) * (n-2) * ..... * 3 * 2 * 1$

In this case, n = 10

$10! = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1$

$10! = 3628800$

Hence, there are 3628800 possible number of arrangements
