      /*It is impossible to consistently get 50% with a finite number that is not infinity. As the number 
      of flips increases, the probability gets closer and closer to 50%. Thereford, in this case where we 
      use an integer for the number  of flips, the max number of flips is 2,100,000,000 which will give us 
      the closest probability consistently to 50%. 
      /*Ros and Guil Probability Quotes: 
      A weaker man might be moved to re-examine his faith, if in nothing else at least in the law of probability
      It must be indicative of something, besides the redistribution of wealth. (He muses.) List of possible
    One: I'm willing it. Inside where nothing shows, I'm the essence of a man spinning double-headed
 coins, and betting against himself in private atonement for an unremembered past.
    Two: time has stopped dead, and a single experience of one coin being spun once has been repeated ninety times... (He flips a coin, looks at it, tosses it to ROS.) On the whole, doubtful. 
 Three: divine intervention,that is to say, a good turn from above concerning him, cf. children of Israel, or retribution from above concerning me, cf. Lot's wife. 
 Four: a spectacular vindication of the principle that each individual coin spun individually (he spins one) is as likely to come down heads as tails and therefore should cause no surprise that each individual
time it does. (It does. He tosses it to ROS.)
