Marginal probability from joint probabilities

WebJul 21, 2024 · The probability that Alice and Bob's outputs equal ( − 1)ab given a and b is the Bell-CHSH correlation V, where a and b are Alice and Bob's inputs correspondingly. Bell's Theorem states that V ≤ 0.5 for a local hidden variables theory. But in quantum mechanics, V can be as big as about 0.85, and this is supported by experiments.

WebDec 21, 2024 · A joint probability distribution simply describes the probability that a given individual takes on two specific values for the variables. The word “joint” comes from the fact that we’re interested in the probability of two things happening at once. For example, out of the 100 total individuals there were 13 who were male and chose ... Suppose that the probability that a pedestrian will be hit by a car, while crossing the road at a pedestrian crossing, without paying attention to the traffic light, is to be computed. Let H be a discrete random variable taking one value from {Hit, Not Hit}. Let L (for traffic light) be a discrete random variable taking one value from {Red, Yellow, Green}. Realistically, H will be dependent on L. That is, P(H = Hit) will take different values depending on …
