If I remember high school math correctly, The first digit can be anything so, 10/10 options, the second digit cant be be the first so only 9/10 options, then 8/10 for the third, continue this pattern for each digit and multiply together you get 1.8% chance.
Someone figure out the probability!

10 x 9 x 8… etc. yields 1,814,400 possible combinations of no repeats, right? I’m confused what the “whole” is if this is expressed as a percent.
100 000 000, the number of possible serial numbers.
Aha, that makes sense. Thanks.
