Question

Colleen is making raffle tickets for the school's give-away drawing. She wants to use the digits 2, 5, and 7 to make three-digit numbers. How many different three-digit numbers can she make if she uses each digit once?

Answer 1

Answer:

You can make 9 three Digit numbers

Step-by-step explanation:

The 9 three digit numbers are:

257

275

752

725

527

572

This can also be easily found out by multiplying the number of digits to the number of digits needed for the number, in this case, there are 3 digits, and the number must have 3 digits in them (without them repeating).

3 digits x 3 needed for the numbers  = 9 three digit numbers
