There are three coins, one coin is gold on both sides (GG), another coin is silver on both sides (SS), and the remaining coin is gold on one side and silver on the other (GS). Each of these coins is in its own drawer. You are asked to open one drawer. When you open the drawer you are looking at the GOLD side of one of the coins. What is the probability the other side of the coin is also GOLD?
