- When a single die is thrown, there are six possible outcomes: 1, 2, 3, 4, 5, 6. The probability of any one of them is 1 6 In general: Probability of an event happening = Number of ways it can happen Total number of outcomes Number of ways it can happen: 1 (there is only 1 face with a "4" on it)www.mathsisfun.com/data/probability.html
