How may 5 digit odd numbers can be formed from 1 2 3 4 5?

• Since the number is odd last digit is 1,3,or 5
  
  When last digit is 1 , remaining 4 digits can be arranged in 4!= 24 ways
  Similarly when last digit is 3, number of ways = 24
  and last digit 5, number of ways = 24
  
  Total number of 5 digit odd numbers = 24*3 = 72

• with repetition=(5*5*5*5*3)= 1875 ways
  without repetition= (1*2*3*4*3)= 72 ways

• 1.without repetition: last digit should be an odd number then only number is odd
  - - - - 1
  4 3 2 1 ways we can arrange total = 4*3*2*1=24 ways
  we have odd numbers 3, so total no of ways = 24*3=72 ways
  1.with repetition: last digit should be odd number
  - - - - 1
  5 5 5 5 ways we can arrange total = 5*5*5*5=625 ways
  we have odd numbers 3, so total no of ways =625*3=1875 ways
