What is the probability that a number selected from 1 to 25

A number is selected from 1 to 25

TO FIND: Probability that, the number is a prime

Total number is 25

Numbers from 1 to 25 that are primes are 2, 3, 5, 7, 11, 13, 17, 19 and 23

Total numbers that are primes from 1 to 25 is 9

`"We know that PROBABILITY" = "Number of favourable event"/"Total number of event"`

Hence probability of getting a prime number from 1 to 25 is equal to `9/25`
