MECE (Mutually Exclusive Collectively Exhaustive) MECE is a principle used by management consulting firms to describe a way of organizing information. . 0.50 c. 1.00 d. Cannot be determined from the information given. Yee yee! The events "even" (2,4 or 6) and "not-6" (1,2,3,4, or 5) are also collectively exhaustive but not mutually exclusive. First, the categories (response options) must be mutually exclusive, which means they do not overlap with one another. Collectively Exhaustive. A set of events are mutually exclusive if the probability of each event in the set is not affected by the outcomes of the other events. If two events are collectively exhaustive, what is the probability that both occur at the same time?

For example, the outcomes of 1 and 4 on rolling six-sided dice, are mutually exclusive events (both 1 and 4 cannot come as result at the same time) but are not collectively exhaustive (it can result in distinct outcomes such as 2,3,5,6). 1. While tossing the coin, both the outcomes are collectively exhaustive which suggests that at least one of the results may take place. If two events are mutually exclusive, it means that they cannot occur at the same time. In some forms of mutual exclusion only one event can ever occur, whether collectively exhaustive or not. classical approach. Mutually exclusive and collectively exhaustive events contain all outcomes of a sample space, and they do not share any common outcomes. The events "even" (2,4 or 6) and "not-6" (1,2,3,4, or 5) are also collectively exhaustive but not mutually exclusive. Proof: The addition law of probability states that for two events A A and B B, the probability of at least one of them occuring is: P (A∪ B) = P (A)+P (B)−P (A∩B).

Second, survey response options must be collectively exhaustive, meaning they provide all possible options that could comprise a response list. Generally when you study probability theory, you spend quite some time studying things related to sets (more generally set theory). For instance, when a die that has six sides is rolled, the resulting events will be 6, 5, 4, 3, 2 and 1 (each comprises only of 1 outcome). For example, tossing a particular biscuit for a .
