You pick a card from a standard deck, look at it, then pick a second card. Since a standard deck of 52 cards has 13 hearts and 13 diamonds, is the probability of drawing a heart and then a diamond 13 52 · 13 52 ?
A) Yes; because the two events are independent.
B) No; because the two events are not independent.
C) Yes; because the two events are disjoint -- no card is both hearts and diamonds.
D) No; because the two events are not disjoint -- a card can be both hearts and diamonds.

((Went back and it gave me the answer. B) No; because the two events are not independent. Since the first card is not being replaced, the two events are not independent -- there are only 51 cards to draw from for the second card.))
