Question

there are five united states athletes, four russian athletes, three french athletes, and one german athlete. How many rankings of the 13 athletes are there

Answer 1

There are 6227020800 possible rankings

Explanation:

Given

`Athletes= 13`

Required

Number of Rankings

Let the number of athletes be n;

Since each athlete can only take one position at any given instance, the number of rankings is
`n!`

Where
`n = 13`

Substitute 13 for n

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

`13! = 6227020800`

Hence, there are 6227020800 possible rankings
