Probability
The possible results of an experiment are outcomes. When you roll a number cube, there are 6 possible outcomes: rolling a 1, 2, 3, 4, 5,or 6. An event is an outcome or a collection of outcomes, such as rolling a 2, or rolling an even number.
Once you specify an event, the outcomes for that event are called favorable outcomes. The favorable outcomes for rolling an even number are rolling a 2, rolling a 4, and rolling a 6.
In mathematics, the chance of occurrence of an event can be measured by a number called the probability.
