How to find the # of possilibities?

  1. Oct 27, 2004 #1
    If I have a combination of numbers and letters (number-letter-number - examples: 1j5, 3f5) then how can I find the number of possibilities?

    So, number-10 possibilities, letter-26 possibilities, number-10 possibilities.

    Thanks!

    If we're talking permuataions (edited to add I know you siad combinations which are different, but you implied some sort of order) here it's simply 10*26*10 = 2600
