Question

What is the probability of rolling an odd or non-prime number using a 12-sided die?

Answer 1

Answer:

D) 11/12

Step-by-step explanation:

From 1 to 12, 6 numbers are odd (1, 3, 5, 7, 9, and 11).

7 numbers are non-prime (1, 4, 6, 8, 9, 10, and 12).

2 numbers are both odd and non-prime (1 and 9).

Therefore, the probability is:

(6 + 7 − 2) / 12 = 11/12
