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

A regular six-sided die is cube-shaped, with faces labelled one, two, three, four, five, and six. The probability of an event occurring can be written as a fraction. The numerator is the number of successful outcomes, and the denominator is the number of possible outcomes.

In this case, the number of possible outcomes is six, as there are six faces on the die. There is only one successful outcome, when the die lands on number three. We can therefore say that the probability of scoring a three on a regular six-sided die is one-sixth or one in six.
