, 3. Two events are independent if the probability of one event is influenced by whether or not the other
event occurs.
FALSE
Independence of events means there is no influence.
AACSB: Reflective Thinking

Topic: Probability, Sample Spaces, and Probability Models
4. Mutually exclusive events have a nonempty intersection.
FALSE
Mutually exclusive events do not intersect (have no sample spaces in common).
AACSB: Reflective Thinking
Blooms: Remember
Difficulty: 2 Medium
Learning Objective: 04-03 Use elementary probability rules to compute
probabilities.
Topic: Probability and Events
5. A subjective probability is a probability assessment that is based on experience, intuitive judgment, or
expertise.
TRUE
AACSB: Reflective Thinking
Blooms: Remember
Difficulty: 2 Medium
Learning Objective: 04-01 Define a probability, a sample space, and a probability model.
Topic: Some Elementary Probability Rules
6. The probability of an event is the sum of the probabilities of the sample space outcomes that correspond
to the event.
TRUE
AACSB: Reflective Thinking
Blooms: Remember
Difficulty: 2 Medium
Learning Objective: 04-02 List the outcomes in a sample space and use the list to compute
probabilities.
Topic: Probability, Sample Spaces, and Probability Models
7. If events A and B are mutually exclusive, then P(A|B) is always equal to
zero.
TRUE

TRUE
AACSB: Reflective Thinking
Blooms: Remember
Difficulty: 1 Easy
Learning Objective: 04-03 Use elementary probability rules to compute probabilities.
Topic: Conditional Probability and Independence
10. Events that have no sample space outcomes in common, and therefore cannot occur simultaneously,
are referred to as independent events.
FALSE
This is a definition of mutually exclusive events.
AACSB: Reflective Thinking
Blooms: Remember
Difficulty: 2 Medium
Learning Objective: 04-04 Compute conditional probabilities and assess
independence.
Topic: Conditional Probability and Independence
11. The method of assigning probabilities when all outcomes are equally likely to occur is called the
classical method.
TRUE
