Events A and B are independent if:
A. event A occurs, therefore event B cannot occur.
B. event B can occur only if event A occurs.
C. the probability of event A is equal to the conditional probability of event A given B.
D. the probability of event A is less than the conditional probability of event A given B.
For two independent events, if P(A)=3/8, and P(B)=8/9, what is P(A and B)?
When two or more events can occur concurrently, it is known as:
A. independent probability.
B. conditional probability.
C. joint probability.
D. the special rule of addition.
If P(A and B)=0.24 and P(A)=0.48, what is P(B|A)?
D. Not calculable without additional data.
A prior probability is assigned to an event:
A. to determine joint probability.
B. to determine subjective probability.
C. for conditional probability problems.
D. when using Bayes’ theorem.
A mortgage company has found that 2% of its mortgage holders default on their mortgage. Furthermore, 90% of those who default are late on at least two monthly payments over the life of their mortgage as compared to 45% of those who do not default. What is the probability that a mortgagee with two or more late monthly payments will default (using Bayes theorem)?
What is eight factorial (8!) equal to?
D. 7! * 1!
