How many vehicle registration plate numbers can be formd with digits 1,2,3,4,5 (no digit being repeated)if it's given that registration number can have 1 to 5 digits ?

• Since there is no repetation allowed
  Trerefore ,
  Registration no. with one digit=5p1
  Registration no. with two digits=5p2
  Registration no. with three digits=5p3
  Registration no. with four digits=5p4
  Registration no. with five digits=5p5
  No. of vehicles=5p1+5p2+5p3+5p4+5p5.
  =5+20+60+120+120
  =325.
