Question

How many unique ways can the letters for M-A-X-I-M-U-M be arranged?

Answer 1

140.

Explanation:

There are a total of 7 letters containing 3 M's .

The answer is 7! / 3!

= 7 * 5 * 4

= 140 ways.

Answer 2

5040

Explanation:

Because every letter can go to 1 spot less. For example: M in the beginning can go everywhere, then the next letter can only go to 6 places because the M got a spot and so on with the other letters, so it would be 7x6x5x4x3x2x1 which is 5040
