Question

marbles numbered from 1 to 12 are put in a bag. if marbles are not put back into the bag after being drawn, what is the probability of drawing two prime numbers in a row?

Answer 1

Answer: 0.1515

Step-by-step 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
