A student goes to the library. Let events B = the student checks out a book and D = the student checks out a DVD. Suppose that P(B) = 0.40, P(D) = 0.30 and P(B AND D) = 0.20.
a. Find P(B|D).
b. Find P(D|B).
c. Are B and D independent?
d. Are B and D mutually exclusive?

Use the following information to answer the next exercises. The graph shown is based on more than interviews done by Gallup that took place from January through December . The sample consists of employed Americans years of age or older. The Emotional Health Index Scores are the sample space. We randomly sample one Emotional Health Index Score.
What is the probability that an Emotional Health Index Score is less than given that it is already less than.
What is the probability of rolling a prime number of dots with a fair, six-sided die numbered one through six?
Use the following information to answer the next two exercises. You see a game at a local fair. You have to throw a dart at a color wheel. Each section on the color wheel is equal in area.

Let B = the event of landing on blue.
Let R = the event of landing on red.
Let G = the event of landing on green.
Let Y = the event of landing on yellow.
If you land on red, you don’t get a prize. What is P(R)?
