Consider an enhanced version of the casino game of roulette called turbo-red roulette that features 38 colored and numbered pockets on a spinning wheel with a total of 20 red pockets and 18 black pockets. A $1 bet on red wins $1 if the ball falls on red and loses $1 otherwise (i.e., if the ball falls on a black pocket). 

You spin the roulette wheel 10 times, betting on red each time. 

Use the central limit theorem to Find an approximation to the probability that your total winnings after 10 $1 bets are greater than zero?
