Answer to Question 1

Clearly X and Y are independent since P(x,y) = P(x).P(y) for all pairs (x,y).

Answer to Question 2

S = Capital punishment supporter
F = Female
P(S  F) = P(S  F)  P(F) = (0.46 )(0.48 ) = 0.2208
P(F  S) = P(F  S) / P(S) = 0.2208 / 0.64 = 0.345

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
