Step-by-step explanation:

If we make a two-digit number from the numbers 2, 3, 5, 7, 9 without repeating the numbers, then find the probability of the following events.

(1) That number will be odd.

(2) It will be a multiple of 5.  

  • So the two digit numbers that can be formed from the given digits will be as follows.
  •                 2,3,5,7,9
  • 22,23,25,27,29
  • 32,33,35,57,39
  • 52,53,55,57,59
  • 72,73,75,77,79
  • 92,93,95,97,99
  • The total number of digits will be 25, out of which odd numbers are 20
  • Therefore the probability that an odd number is formed will be 20/25 = 4/5
  • Now numbers that are multiple of 5 are 5
  • So the probability that it will be a multiple of 5 will be 5/25 = 1/5
