Question

List the sample space for a three digit number formed from the digits 1,9,5 and 3 with no digit to be used more than once

Answer 1

Answer:

15625 possibilities

Step-by-step explanation:

So, possible number of five-digit numbers that can be formed = (5^5) = 3125. So, for these 3125 five-digit numbers, sum of the digits at each place = (3125 / 5) * (1 + 3 + 5 + 7 + 9) = (625 * 25) = 15625.
