The Lottery Game
Can You Predict What Will Happen Next?
What does "RANDOM" mean? Think carefully before you answer! The definition may not be as obvious as you think. After checking the dictionary definition, consider the following four statements... which ones do you think are true?
The experiments and models you will find on this site can be summarized in seven words: The growth of order out of randomness. The world around and within us is filled with randomness. Yet instead of being torn apart by this randomness, nature survives and thrives on it. How can this be? Before we can begin to answer this question, we must study randomness itself.
Is the present always influenced by the past? Suppose you are flipping a coin and, by chance, flip four heads in a row. Does flipping three heads in a row affect the next flip - the fifth flip - why or why not? Is the fifth flip more likely to be another head? Or is the fifth flip less likely to be a head?
Try out the Lottery Java Applet. Click on "Flip 4 Same" which will flip until either 4 heads or 4 tails are flipped in a row. Now choose one of these above strategies and stick to it.
Is your strategy a winner? A loser? Or do you break even?
