See how much money you can win on this addictive game! To calculate the probability each time work out first how many card are left and put this number on the bottom of the fraction. Then work out how many cards that haven’t been turned over yet are higher or lower than the last card. Put this number on the top.Sometimes you will be certain that the next card is higher or lower because all the cards that are higher have already been turned over. If you are certain then it is worth wagering all the money. If the probability is nearer to a half only gamble a small amount of money. This way you should soon become rich!
