How many numbers of six digits can be formed from the digits 1, 2, 3, 4, 5, 6 (no digit being repeated)? How many of these are not divisible by 5?

• 6 digit without repeatation =6!=720
  divisible by 5 end with 5 so 5!=120
  720-120=600 not divisible by 5

• 1) Number of Six digit forms = 6! = 720
  2) The Numbers are divisible by 5 = 5! =120
  Then the number is not divisible by 5 = 720 - 120 =600
