In probability, an event is an outcome or defined collection of outcomes of a random experiment. Since the collection of all possible outcomes to a random experiment is called the sample space, so another definition of an event is that it is any subset of a sample space. The likelihood of occurrence of an event is called probability.
There are many events associated with the sample space. Some of the important events are listed below:
Equally likely Events
When the events have the same probability of happening, then they are called equally likely events. The results of a sample space are called equally likely if all of them have the same probability of occurring.
The following are some examples of likely outcomes:
- Getting 33 and 55 on throwing die
- Getting an even number and an odd number on a die.
