The number of 5-digit numbers that can be formed if the last digit is odd and no digits can be repeated is. Assume that a 5 digit number cannot start with a
'0'

13,440

Step-by-step explanation:

10 possible digits 0 - 9

5 possible numbers for position 5  (odd digits only)

8 possible numbers for position 1  (cannot be zero or the odd number selected for position 5)

8 possible numbers remain for position 2 (10 minus 2 already selected)

7 possible numbers remain for position 3 (10 minus 3 already selected)

6 possible numbers remain for position 4 (10 minus 4 already selected)

5•8•8•7•6 = 13,440
