Chapter 3: Probability

possible outcomes

Mutually exclusive events: two events that can not occur at the same time Topic 3.3: The Product Rule A sample space diagram is another way of showing all the ________ of an event Independent events: two events A and B, if the occurrence of one does not affect the chance that the other occurs, then they are independent events Productruleforindependentevents: P (A n B)= P (A) x P (B) Topic 3.4: Conditional Probability In general for two events A and B the probability of A occurring given that B has occurred can be found using P (AnB) P (AIB)= P (B)

For any two events A and Intersection

the overlapping probability of two events happening In general, if A and Bare mutually exclusive, then
