So, for each of the 5 possibilities for the first digit, there are a further 4 options for the second digit, with 3… 2…1 options for the next digits. Therefore, we multiply the number of options at each step i.e. 5x4x3x2x1 = 120. So, there are 120 “combinations”, or I should say, permutations of “12345”.
