Question

Elliot wrote a computer program that randomly generates a number from 2 to 10. If he runs the program twice, what is the probability that the number generated both times is a prime number? StartFraction 2 over 15 EndFraction StartFraction 1 over 6 EndFraction StartFraction 16 over 81 EndFraction StartFraction 9 over 20 EndFraction

Answer 1

C- 16/81

Explanation:

edge 2021

Answer 2

StartFraction 16 over 81 EndFraction

Explanation:

There are 4 prime numbers from 2 to 10 (2, 3, 5, 7) and 9 numbers from 2 - 10. Total possibilities: 9 * 9 = 81

Prime possibilities: 4 * 4 = 16

Therefore the answer is 16/81 or StartFraction 16 over 81 EndFraction
