With most coins, if you flip them, you will have a slightly better chance of getting tails than heads. This is because coins usually have a bust or portrait on the obverse which makes that side a wee bit heavier than the weight provided by the design on the reverse. If you were to flip a U.S. penny (the kind with the Lincoln Memorial on the back) 1,000 times, it would probably come up heads about 495 times and tails 505.
Wha???! Everything they ever taught us about probability in math at school was wrong?!
ReplyDeleteI can't believe that anything taught in school could possibly be wrong.
