CHAPTER 3- PROBABILITY.
Designed to boost confidence and grades!
Probability Experiment - Answer: an action, or trial, through which specific results are
obtained
Outcome - Answer: the result of a single trial
Sample Space - Answer: the set of all possible outcomes
Event - Answer: a subset of the sample space; may consist of one or more outcomes
Tree Diagram - Answer: a visual display of the outcomes of a probability experiment by
using branches that originate from a starting point
Simple Event - Answer: an event that consists of a single outcome
Fundamental Counting Principle - Answer: if one event can occur in m ways and a
second event can occur in n ways, then the number of ways the events can occur in
sequence is m*n
Classical Probability - Answer: used when each outcome a sample space is equally
likely to occur
Empirical Probability - Answer: based on observations obtained from probability
experiments
Subjective Probability - Answer: result from intuition, educated guesses, and estimates
Complement of an Event - Answer: the set of all outcomes in a sample space that are
not included in the event
