A Prime number is a number in N that has exactly two different numbers in N that divide it: 1 and itself.
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47 are the prime numbers from 1 to 50
Probability of prime from 1 to 50 is 15/50 = 3/10
Probability of not prime is the complement = 1- 3/10 = 7/10
