Lesson 2 Summary

 

In this lesson you solved problems that involved mutually exclusive, non-mutually exclusive, and complementary events. You also calculated the probability associated with those events.

 

To summarize, imagine that you have a deck of cards. An example of a mutually exclusive event would be selecting a black jack and a red jack at the same time.

An example of a non-mutually exclusive event would be selecting a heart and a queen at the same time.

An example of an event is selecting all clubs from the deck of cards.

Therefore, an example of a complementary event is selecting all non-clubs from the deck of cards.

In the next lesson you will deal with probabilities of events that depend on each other and the probabilities of events that are independent of each other.
