Question

There are 11 seats in a vehicle. How many ways can 11 people be seated if only 2 can drive

Answer 1

They can be seater in 7,257,600 ways

Explanation:

Arrangment formula:

Number of ways that n elements can be arranged, that is, distributed in n places is:

`A_(n) = n!`

In this question:

11 seats(driver and other 10).

Only 2 people can drive.

So

The driver can be 2 people.

The other 10 people are arranged in 10 positions.

`T = 2A_(10) = 2*10! = 7257600`

They can be seater in 7,257,600 ways
