If a license plate can have three numbers and four letters, and the letters and numbers can repeat, how many combinations can there be

Question

The numbers and letters are allowed to repeat.  We are trying to find the combinations.

Answer 1

Since you have 0-9 to choose from for each of the numbers, there are 10 x 10 x 10 = 1000 choices.

 

With 26 letters to choose from, you have 26⁴ choices, or 456,976.

 

Total, there are 456,976,000 combinations.
