Question

Kathleen rolled a number cube that has sides labeled 1 to 6. What is the probability that she rolled a 2 or a 4?

Answer 1

Answer:

The probability of rolling any single number is 1/6

there are two outcomes which are mutually exclusive, therefore we add the probabilities:

1/6 + 1/6 = 1/3

Answer 2

in both the cases the probability is 1/6

and the overall probability is 1/3

{ 1/6 + 1/6 = 1/3 }
