Using the Complement to Calculate Probability
:
Sometimes calculating probability can be fairly complicated, but we have tricks to make it easier. Calculating probability of the complement of an event can be easier than calculating the probability of the event itself. We can use the probability of the complement to find the probability of the event by subtracting it from one. This trick is often used when calculating the probability of multiple events.
The following video shows another example of calculating the probability of complementary events.
