kenndra was able to calculate the total number of 3-digits numbers that can be formed from a given set of noon-zero digits without repetition. if there were 60 numbers in all, how many digits were actually given

to kendra?

The answer is 6 digits. There are 6 possible digits (0-9) and each digit can be used only once, so the total number of 3-digit numbers that can be formed is 6 x 5 x 4 = 60.
