Look at this email I received from a company called ;Wisegeek' they send out interesting news items each day .. "If you spin a clean, new Lincoln penny, it will fall tails-side up about eight times out of 10. Forget what you know about statistical probability. If Persi Diaconis and researchers at Stanford University are right, spinning a standard-issue penny (the one with the Lincoln Memorial, clean and shiny) will come up tails side up roughly 80 percent of the time -- not 50-50, give or take a percent either way, as we’ve all come to expect. The reason: The side with Lincoln’s head is a tad heavier than the other side, causing the coin’s center of mass to be slightly skewed. And so, the spinning coin tends to fall toward the heavier side more often, leading to significantly more “tails.” " This, I am certain, is rubbish ....Thoughts?
