Question

Becky is rolling a number cube with the number 1 through 6 what is the probability she will roll a 4 or 5

Answer 1

1/6 since there are 6 sides, therefore, there is a 1/6 chance that any number will be rolled

Answer 2

Probability of rolling 4: 1/6. Probability of rolling 5: 1/6. Since it is an “or” question, you add the probabilities. So 1/6+1/6=2:6= 1/3.
