Question

If you have a four digit code, where each digit can be any number from 0-9, what is the total number of possible four digit codes? Explain.

Answer 1

Exactly 10,000 it’s hard to explain though it’s really complicated

Answer 2

10,000 possible combinations. If there are 10 numbers you can choose from, and it's a 4 digit code, you multiply 10 4 times

10 x 10 x 10 x 10 = 10,000
