WebbWhat is the probability that the sum of these dice is 10 10? Solution: The event for which I obtain a sum of 10 is \ { (4,6), (6,4), (5,5) \} {(4,6),(6,4),(5,5)}. And there is a total of 6^2 = 36 62 = 36 possible outcomes. Thus the probability is simply \frac3 {36} = \frac1 {12} … Webbthat you need in order to use the total law of probability to compute the probability that a test comes out positive, and there’s no other way to know this probability. Remark 2. For all the following questions, the easiest way to think about them is to draw the tree diagram. Please do so when you try to do them, or when you read the solutions
WebbProbability is traditionally considered one of the most difficult areas of mathematics, since probabilistic arguments often come up with apparently paradoxical or counterintuitive results. Examples include the Monty Hall paradox and the birthday problem. Probability can be loosely defined as the chance that an event will happen.
