Probabilistic Independence

Question

Explain what it is meant by two random variables X and Y are probabilistically independent.

Answer 1

P(X/Y)= P(X)

P(Y/X)= P(Y)

one event occurring does not affect the probability of the other event occurring

whether Xi has brown rice for dinner on Alaska's primary election day, doesn't affect whether Sarah Palin wins in Alaska (except for chaos theory)
