What is a simple event in probability?
Probability of Simple Events. A simple event is an event where all possible outcomes are equally likely to occur. So the probability of simple events will have all possible outcomes equally likely to happen or occur. For example, when you toss a coin, there are two possible outcomes – heads or tails, and the probability of heads or tails is equal.
