Fundamental Counting Probability

Dependent Events

• Two or more events in which the outcome of one event affects the outcome of other events

• The chance that some event will happen. It is the ratio of the number of favorable outcomes to the number if possible outcomes

• A ratio that compares the frequency of each category to the total

• The set of all possible outcomes of a probability experiment
