How many 3 digit numbers can be formed with digits 1 2 3 4 5 if no digit occurs twice within the same number?
60.
If any of the numbers 1-5 can be in the first position, there are 5 possibilities for that spot. Since whichever number is in the first position can't be used again, that leaves 4 numbers possible for the second spot. Again, since whatever is in the middle can't be used for the last number, that leaves 3 possibilities.
5X4X3= 60
