If I roll a regular six-sided die, what is the probability that the score is four?
00:00:07.920 --> 00:00:13.480
A regular six-sided die is a cube with six faces.
00:00:13.920 --> 00:00:22.080
They have the numbers one, two, three, four, five, and six.
00:00:22.720 --> 00:00:31.480
The probability of an event occurring can be written as a fraction: the number of successful outcomes divided by the number of possible outcomes.
00:00:32.120 --> 00:00:36.640
In this question, we want to work out the probability that the score is four.
00:00:37.200 --> 00:00:42.280
There is one four on a die.
00:00:42.680 --> 00:00:47.000
Therefore, the number of successful outcomes is one.
00:00:47.520 --> 00:00:53.640
There are six numbers on the die, therefore the number of possible outcomes is six.
00:00:54.280 --> 00:01:04.640
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.
