Use the following information to answer the next two exercises. The following are real data from Santa Clara County, CA. As of a certain time, there had been a total of 3,059documented cases of AIDS in the county. They were grouped into the following categories:

Suppose a person with AIDS in Santa Clara County is randomly selected.

a. Find P(Person is female).

b. Find P(Person has a risk factor heterosexual contact).

c. Find P(Person is female OR has a risk factor of IV drug user).

d. Find P(Person is female AND has a risk factor of homosexual/bisexual).

e. Find P(Person is male AND has a risk factor of IV drug user).

f. Find P(Person is female GIVEN person got the disease from heterosexual contact).

g. Construct a Venn diagram. Make one group females and the other group heterosexual contact

Approximately 86.5%of Americans commute to work by car, truck, or van. Out of that group, 84.6%drive alone and15.4%drive in a carpool. Approximately 3.9%walk to work and approximately5.3%take public transportation.

a. Construct a table or a tree diagram of the situation. Include a branch for all other modes of transportation to work.

b. Assuming that the walkers walk alone, what percent of all commuters travel alone to work?

c. Suppose that1,000 workers are randomly selected. How many would you expect to travel alone to work?

d. Suppose that 1,000 workers are randomly selected. How many would you expect to drive in a carpool?

Let event A = learning Spanish. Let event B = learning German. Then A AND B = learning Spanish and German.Suppose P(A) = 0.4 and P(B) = 0.2. P(A AND B) = 0.08. Are events A and B independent? Hint: You must show ONE of the following:

鈥� P(A|B) = P(A)

鈥� P(B|A) = P(B)

鈥� P(A AND B) = P(A)P(B)

You have a fair, well-shuffled deck of 52 cards. It consists of four suits. The suits are clubs, diamonds, hearts and spades. There are 13 cards in each suit consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, J (jack), Q (queen), K (king) of that suit. Three cards are picked at random.

a. Suppose you know that the picked cards are Q of spades, K of hearts and Q of spades. Can you decide if the sampling was with or without replacement?

b. Suppose you know that the picked cards are Q of spades, K of hearts, and J of spades. Can you decide if the sampling was with or without replacement?
