Compound eventsTwo or more things happening, together or in sequence.Lesson
Finding a conditional probabilityDividing the chance that both happen by the chance of the event being conditioned on.Lesson
Dependent events and drawing without replacementThe first outcome changes the odds of the second; multiply with the updated probability.Lesson
Independent events and the multiplication ruleWhen one event does not change the chance of the other, multiply the two probabilities together.Lesson
Mutually exclusive events and the addition ruleCannot both happen; their probabilities add.Lesson
Union and intersection of eventsThe union is everything in either event and the intersection is only what is in both.Lesson
