What is the probability of rolling a number between zero and two on a fair die?

A fair die is cubic in shape and, therefore, has six faces. Each of the faces is numbered from one to six, and the opposite faces sum to seven. The probability of an event occurring can be written as a fraction where the numerator is the number of successful outcomes and the denominator the number of possible outcomes.

In this question, we want to roll a number between zero and two. The only number that appears on a die that is between zero and two is one. This means that there is one successful outcome in this event. As there are six numbers in total on the die, there are six possible outcomes. The probability of rolling a number between zero and two on a fair die is one out of six or one-sixth.
