Are You In Need of Probability Help?This lesson provides a thorough study of Probability with Dependent EventsHave you been searching for probability help, specifically with dependent events? If you are new to Algebraclass.com or just starting a probability unit, you may want to take a look at the introductory probability lesson or the lesson on independent events. But... if you are ready to study dependent events, let's take a look at the definition. Dependent EventsTwo events, A and B, are dependent if the outcome of the first event does affect the outcome of the second event. In many cases, the term "without replacement" will be used to signify dependent events. Dependent Events are notated as: P(A,then B) Let's take a closer look at situations with dependent events. Example 1Did you notice how the playing card was not replaced, so the outcomes and sample space were reduced for the second event? The second event is dependent on what happens on the first pick. Since this is theoretical probability and we don't know what would really happen on the first pick, we always assume that the first event happens as stated in the problem. Let's take a look at another example. Example 2We know that there's not a great chance that ALL 4 tires will be defective, but what are the chances that all four tires will NOT be defective? This is one for you to figure out! Check out the practice problem below. Practice ProblemAnswer KeyProbability of dependent events is used pretty often in life. Now, are you ready to experiment?
