Lesson 166 of 171

Students learn that two events are independent if the outcome of the first event does not affect the outcome of the second event. For example, flipping a coin twice. And the probability of independent events can be found by multiplying the probability of the first event times the probability  more...

Students learn that two events are independent if the outcome of the first event does not affect the outcome of the second event. For example, flipping a coin twice. And the probability of independent events can be found by multiplying the probability of the first event times the probability of the second event. For example, when flipping a coin twice, the probability of getting heads then tails is 1/2 times 1/2, which equals 1/4.  less...
