2. If the outcome of event A is not affected by event B, then events A and B are said to be

 

3. The intersection of events A and B is the event that occurs when

 

4. If event A and event B cannot occur at the same time, then A and B are said to be___________________.

 

5. Bayes' Law is used to compute

 

6. An approach of assigning probabilities which assumes that all outcomes of the experiment are equally likely is referred to as the

 

7. Which of the following best describes the concept of marginal probability?

 

8. Suppose P(A) = 0.35. The probability of the complement of A is

.

 

9. If the events A and B are independent with P(A)=0.30 and P(B)=0.40, then the probability that both events will occur simultaneously is

 

10. If A and B are mutually exclusive events with P(A) = 0.30 and P(B)=0.40, then P(A or B) is

 

11. Initial estimates of the probabilities of events are known as
