The drawingDiscrete Mathematics Level 3
You meet a man who has a jar with 100 slips of paper in it.
One of the slips of paper has "25" written on it.
Four of them have "10" written on them.
Four of them have "5" written on them.
Five of them have "2" written on them.
The rest are blank.
He offers you a chance to play a game. If you pay him 1 dollar, you will be blindfolded and then you can pick one of the slips of paper out of the jar. The blindfold will be removed and if the slip has a number on it, he will pay you that amount in dollars. If you draw a blank slip, you don't get any money.
Given that 100 cents = 1 dollar, what is your mathematical expectation in cents if you play this game one time?
