Probability & Sets

2. the set of all possible outcomes of a probability experiment.
6. when two events cannot occur in the same trial at the same time; another word for mutually exclusive.
7. a set in which all elements of the set are also contained within a larger set.
11. an object in a set.
13. the set of elements that belong to two or more sets.
15. An activity that has a defined set of possible outcomes and which can be repeated.
16. the ratio of the number of outcomes in which a specified event occurs, compared to the total number of trials, i.e., not through a theoretical sample space, but an actual experiment.
17. a collection of distinct objects.

1. two events that cannot occur in the same trial at the same time; another term for disjoint.
3. the set of elements that belong to one or both sets.
4. describes how likely an event is to occur. It is a measure between 0 and 1, and can be written as a fraction, decimal, or a percent. The probability of an event is written as P(event).
5. the set containing all objects or elements. All other sets are subsets.
8. the ratio of the number of equally likely outcomes in an event to the total number of possible outcomes.
9. an outcome or set of outcomes in a probability experiment.
10. a possible result of a probability experiment.
12. a set with no elements, denoted by ∅ or { }.
14. the set of all elements in the universal set U that are not in set A.
