Composite numbers are those positive integers who have divisors other than 1 and itself.....
So, it is clear that from 1 to 100 there are so many composite numbers which will be hard for us to count.
So, we will count the non-composite numbers....

Total : 26 non-composite numbers....
Now, Probability of composite numbers from 1 to 100
We have, 100-26 = 74 composite numbers ...
Therefore,
=> Probability(P) = 74/100
=> P = 37/50
ANSWER : 37/50
