There are 12 slips of paper in a hat. I will let you reach in and grab one, without looking. An amount of money is written on each piece of paper. One has $100, two have $50, three have $20, and the rest have $-20. If your paper has a positive amount, I will give you that amount in cash. If you get $-20, you must pay me $20. Calculate the expected value of playing the game.Round your answer to two decimal places and do not use the "$"symbol.
