Question

How many different ways can a family visit Philadelphia, Baltimore, and Washington? 3 6 12

Answer 1

Answer is 6 ways

Explanation:

Given that a family wants to visit three different places as Philadelphia, Baltimore, and Washington.

We have to find the number of ways these three can be visited.

Here this is a question of permutation since order matters.

There are 3 cities and these can be visited in 3P3 ways =3!

=3x2x1 =6 ways

There are in total 6 different ways that the family can visit three different places as Philadelphia, Baltimore, and Washington.

Answer 2

This is a problem regarding permutation.


`P\left(3,3\right)=3!=3* 2* 1=6`

There are 6 different ways.
