Luckily we have the same chance each time we fill up. I say luckily because the same applies every time we walk out the door, hop in the car, Hop on a bike, an aeroplane, a boat, etc etc etc. If it didn't our numbers would all be up pretty soon.

Someone needs to do probability 101 again.Quote:

You have to get one number between 0 and 99 come up every fill, so I don't see the odds of each fill changing, but the chance of a specific number I haven't had before coming up increases....Quote:

I could see your calculation working if I thought I should get 00 in consecutive fills.
.... Told you it baked my noodle... :D
Off to google some probability calculations...
Every toss of the coin has exactly the same probability 1/2, although in a run of tosses you may move one way or the other but the more tosses the more likely you are to have 50% heads and 50% tails.
With the fuel pump you have 1/100 chance of it stopping on a dollar for every dollar you fill, if you purchase ~$20 you have ~20/2000 chance of it stopping on a dollar value (or 1/100) the next time you fill you have exactly the same probability. The probability doesn't change because each event is discrete.
Cool, are you venturing north? ;)Quote:
