Things to know

Tree Diagram - a method of displaying the probability of independent events  occurring


Complement - The complement of an event is that event not occurring, meaning the opposite of a favorable outcome. The complement is anything that could happen other than what we're looking for

Dependent events - the occurrence of one event changes the probability a second occurs

Independent events - if one event happens, it does not affect the probability that the second happens
