Expectations probability
WebExpectation is a related term of probability. As nouns the difference between expectation and probability is that expectation is the act or state of expecting or looking forward to … WebThe mathematical expectation of an event that has probability of success p and probability of failure q is defined as pq. If, in addition, the event has probability r of remaining unresolved, only the objective utility function permits the retention of pq as defining the mathematical expectation.
