How many Three digit numbers less than 600 can be formed from the digits: 2,3,5,6 & 8. W/ no repetitions allowed.

asked by Weaam
  1. since our number has to be < 600, the lead digit can only be
    2, 3, or 5
    So we have 3 choices for the lead digit, one has been used up leaving 4 digits left for the middle and 3 digits for the unit digit

    number of such numbers = 3 x 4 x 3 or 36 numbers
