How many three digit numbers can be formed using 2,3,4 and 5 with none of the digits being repeated

• 1st position can be filled by 4 ways,2nd place can be filled by 3 ways and 3rd place can be filled by 2 ways.
  total no. of ways= 4*3*2=24

• ans is :4p3
• 10 years agoHelpfull: Yes(3) No(2)
• if the repeat is allowed then it will be....4*4*4=64ways
  ans if the repeat is not allowed then 4*3*2=24ways

• 4*3*2=24 ways as the first place is occupied in 4ways and 2 place in 3 ways and 3rd place in 2 ways.

• given four numbers 2,3,4,5 by using any of these numbers 3 at a time should form 3 digit number so the ans is 4p3=4*3*2*1=24

• 24 ways
  1st position can be filled in 4 ways,
  2nd in 3 ways(as digits shouldn't be repeated),
  and 3rd place in 2 ways (leaving the digits filled in 1st and 2nd position)
  so 4*3*2=24

• 4p3 is anz
• 10 years agoHelpfull: Yes(0) No(1)
• ans 24
  1st digit can be filled in 4 ways
  2nd '' '' '' '' '' 3 '
  3rd '' '' '' '' '' 2 "
  so 4*3*2=24

• 3 digits can be taken from 4 numbers i.e(2,3,4,5) in 4c3 ways, and those 3 number can be arranged in 3! ways. so, the answer is 4c3*3!.

• 4 numbers... 3 digit number to be formed
  4 * 3 * 2=24 ways without repeat.

• 24 bcz 4*3*2 possibilities
• 5 years agoHelpfull: Yes(0) No(0)
• the sets are (2,3,4),(3,4,5),(4,5,2),(5,2,3).
  3!+3!+3!+3!=4*6=24.
