3. A finance office orders paper supplies from one of three vendors, V1, V2 or V3. Orders must be placed on two successive days, one order per day. Thus, (V2, V3) could denote that the V2 seller gets the order on the first day and the V3 seller gets the order on the second day.

a) Indicate the sample points in this experiment of requesting paper in two successive days.

b) Suppose sellers are randomly selected each day and probability is assigned to each sample point.

c) Denote with A the event that the same seller obtains both orders and B the event that V2 obtains at least one order.

d) Find P(A), P(B), P(A B) and P(A B) by assuming the probabilities of the sample points in these events.

4. Two additional jurors are needed to complete a jury for a criminal trial. There are six prospective jurors, two women and four men. Two of the jurors are randomly selected from among the six available.

a) Define the experiment and describe a sample point. Suppose it is necessary to describe only the two selected juries and not the order in which they were chosen.

b) Indicate the sample space associated with this experiment.

c) What is the probability that the two selected jurors will be women?
