| Question | Answer |
|---|---|
| a union b | set of element that belong to a or b or both |
| a intersect b | set of elements which belong to a and b |
| a prime | set of elemets that are not in set a |
| p of a must be | between 0 and 1 |
| addition rule for mutually exclusive events | p of a union b = p of a + p of b |
| if a and b are independent events then | p of a and b = p of a times p of b |
| general addition rule | p of a union b = p of a + p of b - p of a intersect b |
| conditional probability | p of a given b = p of a intersect b divided by p of b |
| test for independence | p of a given b = p of a and p of a intesect b = p of a times p of b |
