4 choices for the first digit, leaving 3 choices for the 2nd digit.

What is 4 x 3 ?

You might try listing all the possible cases, there are only 12 of them

there are 4 choices for each digit. So there are 4*4 = 16 pairs possible.

Now, if there are no repeats, then there are 4 choices for the 1st, but only 3 for the second, making 4*3 = 12 possible numbers.

Go with Steve's solution, since there was no mention of "no repeats allowed."

I sort of imagined the numerals 3, 5, 7, and 9 lying there to be sewn on the jersey.
