The Data Below Show the Types of Medals Won by Athletes

The data below show the types of medals won by athletes representing the United States
in the Winter Olympics. Suppose that one medal is chosen at random and the type of
medal noted. $$\begin{array} { l l l l l l l } \text { gold } & \text { gold } & \text { silver } & \text { gold } & \text { bronze } & \text { silver } & \text { silver } \\\text { bronze } & \text { gold } & \text { silver } & \text { silver } & \text { bronze } & \text { silver } & \text { gold } \\\text { gold } & \text { silver } & \text { silver } & \text { bronze } & \text { bronze } & \text { gold } & \text { silver } \\\text { gold } & \text { gold } & \text { bronze } & \text { bronze } & & &\end{array}$$ Given that the medal is not bronze, what is the probability that the medal is gold?
