You look at a carnival game. The person running it says, "Just reach your hand into this bag. There are 9 yellow balls and 1 red ball in the bag. You get 4 chances to pull out the red ball. (You have to put the ball you drew back before you draw another ball.) You only have to pay one dollar to play, and you get 3 dollars if you pull out the red ball!"

Assuming the person running the game is telling the truth, and the balls only differ in color, would you expect to make a net profit or a net loss on this game?

you have a 90%chance of losing ,although some might think otherwise , you can only consider the present draw for if you pick the proper ball on that there is no need praw again , since you only have a 10%on your current draw the chances of losing is 90%
