Simulate 10000 games

Now, let's simulate 10000 games and answer the following: since 2 and 12 are equally unlikely, how often does either a 2 or a 12 get rolled more than twice within a game?

Basic strategy indicates that the spaces with 2 or 12 should be avoided because they are the least probable, and although this is true theoretically, here we will investigate how surprising it really should be if they end up coming up more frequently than expected. The roll_dice function from previous exercises has been preloaded for you.
