set
26. a collection of items drawn entirely from a single set. This can consist of any number of items from a set ranging from none at all (a null ______) all the way up to the entire set (every set is a ______ of itself)
subset
27. the set of all elements that belong to at least one of the given two or more sets
union of sets
28. the __________ uses multiplication to find the number of ways two or more events can occur. (Two or more events that happen in succession)
counting principle
29. The outcomes for a specified event
favorable outcomes
30. The occurrence of one event does not affect the probability of the occurrence of the other event.
