February 23rd. Someone should verify the statistics. I think if you
have 26 people in a group, the odds are better than 50/50 that two will have the same birthday. I may be wrong.
A bar bet: I hand you a magic penny and tell you clutch it overnight. You wake up the next day (day 1) and you have 2 cents. The next day 4 cents and so on. How much money (not pennies) will you have at the end of 30 days? "Guess....If you come within 50% of the answer, I buy you a drink. If not you owe me a drink."
Let's say they guess $100,000. Take out a calculator and put in 2 x .01 and hit = 10 times. Show $10.24. Double the bet. They say $500,000 (they owe you a second drink. Five more =. Show $327.68. Their guess is wrong.....Another drink they owe you. A total of 20 = shows $10,485.76. Bet. They lose. Keep going.
A penny a day doubled for 30 days = $10,737,417. You've won a lot of drinks. You need the calculator because no one will believe you.
