Answer: 0.1515

Explanation:

The prime numbers from 1 to 12 are 2, 3, 5, 7, 11. This means that there are 5 prime numbers from 1 to 12.

The probability of drawing the first prime number will be: = 5/12

The probability of drawing the second prime number will be: = 4/11

Therefore, the probability of drawing two prime numbers in a row will be:

= 5/12 × 4/11

= 20/132

= 0.1515
