What Are the Tests for Independence in Probability Statistics?

[QUOTE="tnich, post: 6248036, member: 639870"] Right, ##P(A\cap B)## is the probability of the [B]intersection [/B]of events (sets) ##A## and ##B##, and you are correct that if that probability is zero then the events are mutually exclusive. The tests for independence that you found are correct, and the events are independent. The key concept here is that events are independent if knowing whether one occurred does not change the probability that the other occurred. That is the meaning of ##P(A|B)= P(A)##; the probability of ##A## given that you know ##B## has occurred is the the same as the probability of ##A## without knowledge of ##B##. [/QUOTE]
