A = {getting prime number}
A = {2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97}
n(A)=25 ; n(S)=100
P(A)=n(A)/n(S)
= 25/100
=1/4

1/4 is the Probability that number choosen from 1 to 100 is prime
Step-by-step explanation:
Numbers from 1 to 100 = 100
Prime Numbers = 2 , 3 , 5 , 7 , 11 , 13 , 17 , 19 , 23 , 29 , 31 , 37 , 41 , 43 , 47 , 53 , 59 , 61 , 67 , 71 , 73 , 79 , 83 , 89, 97
= 25 Prime numbers
Probability that number chosen is prime = 25/100
= 1/4
