Question

The game piece shown has 12 sides, labeled 1 to 12.


a. What is the probability of rolling an 11?

b. What is the probability of rolling a number greater than 5?

c. What is the probability of rolling a number greater than 12?

Answer 1

Assuming the 12 sides are equally likely (1–12):

a. P(11) = 1/12.

b. Numbers > 5 are 6–12, seven outcomes, so P(>5) = 7/12.

c. No numbers > 12, so P(>12) = 0.
