All the clubs are taken out of a pack of card Generally when you study probability theory, you spend quite some time studying things related to sets (more generally set theory). Result: As both events have nothing in common therefore, the two events are mutually exclusive events. Each possible outcome (or) element in a sample space is called sample point. When pesticide is applied a pest may survive or die. Mutually exclusive events prevent the second event to take place when the first event appears. For example, when a coin is tossed then the result will be either head or tail, but we cannot get both the results. If two events are 'mutually exclusive' they cannot occur at the same time. The condition for mutually exclusive events for being exhaustive is the outcome of an experiment must be one out of the sample space of mutually exclusive events for that particular experiment. Let A = Event of getting both red cards and B = Event of getting both black cards. Let A be the event that the randomly selected digit is multiple of 5. Cards: Kings and Aces are Mutually Exclusive. MECE, or mutually exclusive and collectively exhaustive, is an approach to analysis that breaks things into mutually exclusive sets that fully describe a domain.
