List of primes under 70
2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67
2/19 primes have 6 in their digits
Therefore there is a [200/19]% chance of randomly picking a prime number under 70 that includes 6 as one of its digits.

First, we have to calculate the number of prime numbers between 0 and 70
1,3, 5, 7, 11, 13, 17, 19, 21, 23, 27, 31, 37, 41, 47, 51, 57, 61, 67 A total of 19 prime numbers
Only two numbers contain the digit 6
Then, the probability is 2 / 19
