There are 5*4*3 = 60 such numbers.

It is possible to create a 3-digit number, without repeated digits so the probability is 1.

Five numbers (5, 6, 7, 8, 9) can be selected for each of the 5 digits. So, there are 5*5*5*5*5 or 55 or 3125 five digit numbers.

The largest 10-digit number with no digit repeated is 9876543210 !
