Probability of Dependent Events - YourTeacher.com - Math Help

For a complete lesson on probability of dependent events, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that two events are dependent if the outcome of the first event affects the outcome of the second event. For example, taking a block out of a jar, then taking a second block out of a jar. And the probability of dependent events can be found by multiplying the probability of the first event times the probability of the second event. For example, if there are 4 blue blocks and 4 yellow blocks in a jar, the probability of taking a blue block out of the jar then a yellow block out of the jar is 4/8 times 4/7, or 16/56, which reduces to 2/7. The reason that the probability of taking a yellow block out of the jar is 4/7 rather than 4/8 is that a blue block has already been taken out, so there are only 7 blocks left in the jar.
