WebbIn our example, both A and B have probability 4/8=1/2. An event is simple if it consists of just a single outcome, and is compound otherwise. In the example, A and B are compound events, while the event ‘heads on every throw’ is simple (as a set, it is {HHH}). If A = {a} is a simple event, then the probability of A is just the probability ...

Webb10 mars 2024 · Probability examples Here are some sample probability problems: Example 1 There are six blocks in a bag. Three are yellow, two are blue and one is red. What is the probability of picking a blue block out of the bag? First, you find the number of favorable outcomes, or blue blocks, which is two. WebbThe more likely it is that the event will occur, the higher its probability. The probability of an impossible event is 0; that of an event that is certain to occur is 1. The probabilities of two complementary events A and B – either A occurs or B occurs – add up to 1. A simple example is the tossing of a fair (unbiased) coin. grand haven houses for rent
