If I roll a regular six-sided die, what is the probability that the score is four?
A regular six-sided die is a cube with six faces. They have the numbers one, two, three, four, five, and six. The probability of an event occurring can be written as a fraction: the number of successful outcomes divided by the number of possible outcomes.
In this question, we want to work out the probability that the score is four. There is one four on a die. Therefore, the number of successful outcomes is one. There are six numbers on the die, therefore the number of possible outcomes is six.
This means that the probability that the score is four when rolling a regular six-sided die is one-sixth or one out of six.
