Unit 10: Probability
Don’t let what you can’t do stop you from doing what you can do.
Outcome - the result of a single trial of an experiment
Multiplication counting principle - When there are m ways to do one thing, and n ways to do another, then there are m×n ways of doing both
Probability - the extent to which something is probable; the likelihood of something happening or being the case
Compound events - consists of two or more simple events Sample space - the set of all possible outcomes of that experiment
Tree diagram - shows all the possible outcomes of an event
Simple event- an event that consists of exactly one outcome Probability - the extent to which something is probable; the likelihood of something happening or being the case
Compound events - consists of two or more simple events
Independent events - Two events, A and B, are independent if the fact that A occurs does not affect the probability of B occurring.
Dependent events - Two events are dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second so that the probability is changed.
Complementary events - All outcomes that are NOT the event; If the event is Monday or Tuesday, the complement would be the days Wednesday through Sunday.
Mutually exclusive events - Two events are mutually exclusive if they cannot occur at the same time (i.e., they have no outcomes in common)
