Chapter 4 Objectives 1. Determine sample spaces and find the probability  of an event, using classical probability or  empirical probability. 2. Find the probability of compound events, using  the addition rules. 3. Find the probability of compound events, using  the multiplication rules. 4. Find the conditional probability of an event.

Chapter 4 Objectives 5. Find total number of outcomes in a sequence of  events, using the fundamental counting rule. 6. Find the number of ways that r objects can be  selected from n objects, using the permutation rule. 7. Find the number of ways for r objects selected from n  objects without regard to order, using the  combination rule. 8. Find the probability of an event, using the counting  rules.

Probability probability experiment  is a chance process that  leads to well-defined results called outcomes. An  outcome  is the result of a single trial of a  probability experiment. sample space  is the set of all possible outcomes  of a probability experiment. An
