A friend randomly chooses two cards, without replacement, from an ordinary deck of 52 playing cards. In each of the following situations, determine the conditional probability that both cards are aces. (a) You ask your friend if one of the cards is the ace of spades, and your friend answers in the affirmative. (b) You ask your friend if the first card selected is an ace, and your friend answers in the affirmative. (c) You ask your friend if the second card selected is an ace, and your friend answers in the affirmative. (d) You ask your friend if either of the cards selected is an ace, and your friend answers in the affirmative.

Ruth runs a 100-meter race. For parts (a)-(c), make a graph that illustrates each situation.

a. Ruth's official time is 14 seconds.

b. Ruth trips and falls at the beginning of the race. She loses five seconds, so her official time is 19 seconds.

c. Ruth starts running two seconds before the starting gun. Nobdoy notices, and her official time is 12 seconds.

d. Fill in the blank. To get from the graph in part (a) to the graph in part (b), you can apply the rule $(x, y) \rightarrow (x+ \_\_\_, y)$.

e. Fill in the blank. To get from the graph in part (a) to the graph in part (c), you can apply the transformation $(x, y) \rightarrow) (x+\_\_\_, y)$.
