## Balls in a JarProbability puzzles require you to weigh all the possibilities and pick the most likely outcome.
You're walking down a street, when you see some people gambling on the roadside.
The dealer says: "There are 10 black balls and 10 white balls in this jar. You are blindfolded and you randomly pick 10 balls. If 5 of the balls you picked are black and the other 5 are white, you lose $2. Otherwise you win $1." Is the gamble fair? ## What Next?
