Answer 2

Answer:

The natural numbers from 2 - 15 are

2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15

The prime numbers are

2, 3, 5, 7, 11 and 13

So,

$\frac{fraction \: of \: prime \: numbers}{total \: numbers \: from \: 2 \: to \: 15} \\ = \frac{number \: of \: primes}{total \: numbers \: from \: 2 \: to \: 15} \\ = \frac{6}{13}$
