WebSolution Direct proof. There is a straightforward proof of this theorem. As an introduction, recall that if two events are statistically independent, then the probability of both happening equals the product of the probabilities of each one happening independently.For example, if the chance of rain in Moscow on a particular day in the future is 0.4 and the chance of an …
