here's a good one to make a few dollars as you drive through traffic on your way to the casino


offer your passenger a bet at an even $5 that in the next 20 cars you see there will be two whose car number plates end in the same last two numbers


if the car's number is abc123 the 23 is the same as that of a car with 423xyz as its number


there are 100 possible numbers, from 00 to 99, so he will think he has the best of it in only 20 cars


what are your chances of winning each bet?


how many cars would make this a fair game?
