Probability
Random
Complementary event
A simple event is one outcome or a collection of outcomes.
9-2: sample spaces
Sample Space
Tree digoal
Fair game
The set of all of the possible outcomes in a probability experiment is called the sample space.
9-3: The fundamental counting principle
Fundamental counting principle: If event M has m possible outcomes and event N has n possible outcomes, then event M followed by event N has m × n possible outcomes.
9-4: Permutations
A permutation is an arrangement, or listing, of objects in which order is important.
Mid-Chapter quiz
9-5: Combinations
An arrangement, or listing, of objects in which order is not important is called a combination.
9-6: Problem-Solving Investigation
9-7: theoretical and experimental probability
Theoretical Probability
Experimental Probability
Theoretical probability is based on what shoshould happen when conducting a probability experiment. Experimental probability is based on what actually occurred during such an experiment.
9-8: Compound events
Compound event
Independent Events
Dependent events
Disjoint events
Probability of Independent Events
P (A and B) = P (a) · P (B)
Probability of dependent events
P (A and B) = P (a) • P (B following)
