WebbTwo events are independent if the occurrence of one event does not affect the probability of the other one occurring.. Let’s say we have a bag of five marbles: three are red and two are blue. If we select two marbles out of the bag WITH replacement, the probability of selecting a blue marble second is independent of the outcome of the first event. WebbThen, the probability of only A occurring is the probability of A occurring given that only one of the events will occur, or P ( A ∣ S), where S is the event that only one of A and B occurs. Then the answer is P ( A ∩ S) P ( S) = P ( A) P ( A ∪ B) − P ( A ∩ B) = .75 .8 = .9375. This doesn't seem correct or simple enough. Any advice is ...

WebbProbability tells us how often some event will happen after many repeated trials. You've experienced probability when you've flipped a coin, rolled some dice, or looked at a … WebbQuestion 1. A die is rolled, find the probability that an even number is obtained. Solution to Question 1. Let us first write the sample space S of the experiment.
