Now that I got your attention, here is a probability puzzle that requires 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."
