2
Sample space the collection of all possible outcomes of a chance experiment –Roll a dieS={1,2,3,4,5,6}

3
Event any collection of outcomes from the sample space –Rolling a prime #E= {1,2,3,5} –Rolling a prime # or even numberE={1,2,3,4,5,6}

4
Complement Consists of all outcomes that are not in the event –Not rolling a even # E C ={1,3,5}

5
Union the event A or B happening consists of all outcomes that are in at least one of the two events –Rolling a prime # or even number E={1,2,3,4,5,6}

6
Intersection the event A and B happening consists of all outcomes that are in both events –Drawing a red card and a “2” E = {2 hearts, 2 diamonds}

7
Mutually Exclusive (disjoint) two events have no outcomes in common –Roll a “2” or a “5”

8
Venn Diagrams Used to display relationships between events Helpful in calculating probabilities
