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

Question

Possible  answers  are 1/2, 1/6, 1/3, 3/4.

Answer 1

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
