Question

When rolling a number cube with sides labeled 1 through 6, what is the probability of rolling a number greater than 3?

Express your answer in simplest form.

Answer 1

When you roll a die there are 6 possible outcomes, {1,2,3,4,5,6}. Out of those, 3 are greater than three, {4,5,6}. So, 3 out of 6 outcomes match what you're looking for. The answer is 3/6, or, simplified, 1/2.
