Event operations in probability

WebAn event in probability is the outcome or set of outcomes resulting from an experiment. The probability of events ranges between 0 and 1, and it measures how likely it is that an event will happen. Two events (A and B) are independent if the fact that A has happened does not affect the probability of B happening, and vice versa. Two events (A ... WebApr 5, 2024 · A compound event is more complex than a simple event, as it involves the probability of more than one outcome. Another way to view compound events is as a combination of two or more simple events. Consider the probability of finding an even number less than 5. We have a combination of two simple events: finding an even …
