Question

How many ways can 13 students line up for lunch?

Answer 1

The number of ways of doing so is:

6227020800

Explanation:

We know that the number of ways of arranging n people or things or number is done by the rule as:

n!

We know that the formula is given by:

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

Here we are asked to arrange 13 students in a line for a lunch.

So, the number of ways of doing so is calculated as:

`13!`

`13!=13* 12* 11* 10* 9* 8* 7* 6* 5* 4* 3* 2* 1\\\\13!=6227020800`

Hence, the number of ways of doing so is:

6227020800
