Determining whether events are independent
WebFor the experiment, determine whether the two given events are independent. The answers are all guessed on a twenty-question multiple choice test. The events are "the third answer is correct" and " the test answer is correct." These two events are _____ WebSometimes the presence or absence of one event tells us something about other events. whether the others happened. Independent events give us no information about one another; the probability of one event occurring does not affect the probability of the other events occurring. Independent events

WebTwo events are independent events if the occurrence of one event does not affect the probability of the other event. If A and B are independent events, then the probability of A and B occurring together is given by. P (A ∩ B) = P (B ∩ A) = P (A). P (B) This rule is called as multiplication rule for independent events. Step 2: Click the blue ...
