A: Suppose that 90% of adults with allergies report symptomatic relief with a specific medication. If the medication is given to 10 new patients with allergies, what is the probability that it is effective in exactly six?

B: A small voting district has 110 female voters and 90 male voters. A random sample of 10 voters is drawn. What is the probability exactly 8 of the voters will be female?

C: A deck of cards contains 30 cards: 10 red cards and 20 black cards. 5 cards are drawn randomly without replacement. What is the probability that exactly 3 red cards are drawn?

D: The bivariate probability distribution of X and Y is given in the table below.

x	2	4	6
3	.1	.2	.1
5	.15	.25	.2

What is the conditional probability that X=3 given that Y=2?

Are X and Y independent? Explain
