Answer:

  • 648

Step-by-step explanation:

If the number is xyz, we have:

  • x = 1 to 9, total 9 ways
  • y = 0 to 9, total 10 ways minus 1 to prevent repetition, so 9 ways
  • z = 0 to 9, total 10 ways minus 2 ways to prevent repetition, so 8 ways

Total number of possible 3-digit numbers:

  • 9*9*8 = 648
