    considering the betting going on this game..... statically flipping a coin should be 50/50... flip a coin and post the result. or don't i don't care.

    i flipped a nickel... heads

    so do you think when they invented coins they designed them to have equal weight (heads side and tail side) so that there would actually be a 50/50 odd when flipping?? hmmmm

    guessing that 99.9% of the mass is in the center of the coin and when they press them it doesn't significantly alter the weight on either side whether heads or tails.

    typically the side with the head is heavier, making tails show up 50.5% to 49.5% for heads.

    Believe I read that somewhere.

    really? what if a prez has a REALLY big head and to make it look realistic on the coin the head has to have more coin material that whatever tail material??

    lol did Bfactor hack your account?

    i think that because they are pressing the coins, they are actually compressing both sides towards the middle and not actually removing any material from either side. Why are you messing with our heads during the superbore.

    Why not draw red or black from a deck of cards? Same odds no?

    when i was at Chitzanitza, they had a large games courtyard with stone hoops mounted on the side walls ... the guide said it may have been the earliest variation of basketball. Players had a round object they would have to move around the court yard and try to get through the hoop. The round object was usually the head of a fallen warrior they had slain in battle.

    This has nothing to do with coin flips - the guide may have been full of shit. idk.

    While imprisoned by the Germans during World War II, the South African mathematician John Kerrich tossed a coin 10,000 times. Result: 5067 heads, a proportion of 0.5067

    The side you have right side up when you toss it is slightly more likely to hit, assuming you catch and flip.
