Events a and b are independent
WebSpinner A and B shown in the figure are spun at the same time. (a) Are the events "spinner A stops on red” and “spinner B stops on yellow” independent? (b) Find the probability that spinner A stop on red and spinner B stops on yellow. WebIn probability, we talk about independent events, and earlier we said that two events A and B are independent if event A occurring does not affect the probability that event B will occur. Now that we’ve introduced conditional probability, we can formalize the definition of independence of events and develop four simple ways to check whether ...

WebTo find: The probability of getting a 2 or 3 when a die is rolled. Let A and B be the events of getting a 2 and getting a 3 when a die is rolled. Then, P (A) = 1 / 6 and P (B) = 1 / 6. In this case, A and B are mutually exclusive as we cannot get 2 and 3 in the same roll of a die. Hence, P (A∩B) = 0. Using the P (A∪B) formula,
