while driving from his home to his workplace, Chris has to pass through two traffic lights. The general pobability of getting a red signal at the first traffic light (event a) is 36%. the general probability of getting a red signal at the second traffic light (event b) is 25%. The probability of Chris getting a red signal at both thraffic lights is 9%. In this scenario, A and B are -------blank------ events
Notice how P(A and B) = P(A)*P(B) = 0.36*0.25 = 0.09 So because P(A and B) = P(A) *P(B) in this case, this means A and B are independent events. In other words, the fact that A occurs does not alter the probability of event B.
