In probability theory, the law (or formula) of total probability is a fundamental rule relating marginal probabilities to conditional probabilities. It expresses the total probability of an outcome which can be realized via several distinct events, hence the name.

The total probability is 1. We now express this as a double integral: Z. d. Z. b. f(x;y)dxdy = 1. c a. Note: as with the pdf of a single random variable, the joint pdf f(x;y) can take values greater than 1; it is a probability density, not a probability. hat ed sheeran frau
