Brainliest and 39 points how many different 4-digit personal identification numbers (pins) can be made from the digit 0 through 9 if no digits repeat?

You have 10 numbers to choose from, and you're choosing 4 from that pool. Order of the numbers matters, because having 1234 as a PIN is not the same having it be 1324, so we're counting the number of permutations of 10 digits taken 4 at a time. So there are

possible PINs that can be made.
