Answer 1

Answer:

A) 4/5

Step-by-step explanation:

P(not a prime) = 1 - P(a prime)

and

P(a prime) = ( # primes from 51 to 100 ) / 50

So it will do to count primes.

The primes are:

53, 59, 61, 67, 71, 73, 79, 83, 89, 97

There are 10 of them, so

P(a prime) = 10 / 50 = 1/5

=> P(not a prime) = 1 - 1/5 = 4/5
