WebConditional Probability is the likelihood of an event or outcome occurring based on the ... WebCompound Events. An event is an occurrence that can be determined by a given level of certainty. For example, when we say that the probability of an event happening is high or low, we are stating the fact that the event may or may not happen in a given way. The ways in which an event can happen are what we call the outcomes of an event.
