You enter a room with ten bags, each filled with what appears to be gold bars. Your host explains that only one bag contains real gold, and the other nine are worthless and you will get to leave with the bag of your choice.

Real gold bars weigh 11 oz., while fake gold bars weigh 10 oz.


Assume that you can not "feel" or see the difference.

Luckily, there is a scale in the room that gives weight in ounces, but it costs a penny for each use and you only have one penny.

You have one penny and ten minutes....Go...
