If I roll a regular six-sided die, what is the probability that the score is five?

A regular die has six faces numbered one, two, three, four, five, and six. In order to calculate the probability of any event, we can write our answer as a fraction where the numerator is the number of successful outcomes and the denominator is the number of possible outcomes.

There is only one face that has the number five. Therefore, there is one successful outcome. As there are six faces, there are six possible outcomes. Therefore, the probability that the score is five on a regular dice is one out of six or one-sixth.

This probability is the same for any individual number on the die. The probability of rolling a one is one out of six. The probability of rolling two is one out of six, and so on.
