Question

In a probability experiment, a 1 - 6 number cube is rolled once. What is the theoretical

probability of rolling 3 or 5?
A) 1/6
B) 1/4
C) 1/3
D) 1/2

Answer 1

C. The probability of rolling a 3 is a 1/6 chance, as is rolling a 5. But the probability of rolling a 3 OR 5 increases that chance twice as much, make the probability a 1/3 chance.
