Exhaustive Events Exhaustive Event is the total number of all possible outcomes of an experiment. 1) The mathematical theory of probability assumes that we have a well defined repeatable (in principle) experiment, which has as its outcome a set of well defined, mutually exclusive, events. One source of confusion is in counting the number of outcomes, both favorable and possible, such as when tossing coins and rolling dice. There are three relationships in finding the probability of an event: complementary, conditional and mutually exclusive. At least two coin and ii.
