Answer 1

A number is selected at random from the numbers 1 to 30. The probability that it is a prime number is D.11/30

Answer 2

C. 1/3

Step-by-step explanation:

A number is selected at random from the numbers 1 to 30

Total outcomes = 30

Prime numbers between 1 to 30 = 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29

Number of favorable outcomes = 10

Probability of getting a prime number = 10/30 = 1/3

Option C is the answer.
