3] Suppose there are four unmarked boxes, A, B, C, D. Box A contains three gold coins; B contains two gold coins and one silver coin; C contains one gold coin and two silver coins: and D contains three silver coins. Suppose you randomly select one ofthe boxes and pull out a single coin and it is gold.

Give the conditional probability that the gold coin was chosen from box D. c [extra credit 15 points] Let the gold coin remain in your hand. Suppose you get to select a second coin from the same box as you drew the gold coin from. What is the conditional probability that this second coin is also gold?
