题目信息
There are 13 hearts in a full deck of 52 cards. In a certain game, you pick a card from a standard deck of 52 cards. If the card is a heart, you win. If the card is not a heart, the person replaces the card to the deck, reshuffles, and draws again. The person keeps repeating that process until he picks a heart, and the point is to measure how many draws it took before the person picked a heart and, thereby, won. What is the probability that one will pick the first heart on the third draw or later?
A:$$\frac{1}{2}$$
B:$$\frac{9}{16}$$
C:$$\frac{11}{16}$$
D:$$\frac{13}{16}$$
E:$$\frac{15}{16}$$
