| A | B |
| PROBABILITY | the measure of how likely an event is |
| EXPERIMENT | a situation involving chance or probability that leads to results called outcomes |
| OUTCOMES | the result of a single trial or experiment |
| EVENT | one or more outcomes of an experiment |
| PROBABILITY FORMULA | # of ways an event can occur / the total number of possible outcomes |
| PERMUTATIONS | the number of ways items can arranged |
| THEORETICAL PROBABILITY | based on mathematical reasoning |
| EXPERIMENTAL PROBABILITY | based on actual experiments |
| COUNTING PRINCIPLE | uses multiplication to show the number of possible outcomes |
| TREE DIAGRAM | used to show all the possible outcomes of an event in an organized way |
