1. P(E)=

2. Sample Space All possible outcomes for a chance experiment Disjoint – (Mutually Exclusive) They have nothing in common. P(A  B)=0

3. As the number of repetitions of an experiment increases, the experimental (empirical) probability will approach the theoretical (classical) probability.

4. Conditional Probability: If Independent, then:

5. Dependent Independent

6. Independent: Mutually Exclusive: Dependent

7. Independent Mutually Exclusive

8. DoesThey are not independent.

9. A corporation has three methods of training employees. Because of time, space, and location, it sends 20% of its employees to location A, 35% to location B, and 45% to location C. Location A has an 80% success rate. That is 80% of the employees who complete the course will pass the licensing exam. Location B has a 75% success rate, and location C has a 60% success rate. If a person has passed the exam, find the probability that the person went to location B.
