Is flip of a coin merely a luck? Experts don't think so

It turns out one side has a slightly greater likelihood of landing face up
(Web Desk) - Think again before settling a decision on heads or tails in future.
Experts have revealed that flipping a coin is not quite the 50/50 chance we've long believed it to be.
It turns out one side has a slightly greater likelihood of landing face up. The art of flipping a coin dates back to the Roman Empire.
Back then it was "heads or ships". And it's crucial today for a number of things, even in football with the pre-game coin toss.
A huge group of researchers put it to the test by flipping various coins from across the world a staggering 350,757 times.
Some 48 people flipped coins minted in 46 countries to ensure there was no technique bias.
The results found that a coin is 50.8 per cent likely to land on the same side it started on, reports Phys.org.
It backs up a previous study published in 2007 by Stanford mathematician Persi Diaconis.
He claimed that this happens because the coin spends more time on the side it started on while it's in the air.
"The standard model of coin flipping was extended by Persi Diaconis, who proposed that when people flip an ordinary coin, they introduce a small degree of 'precession' or wobble – a change in the direction of the axis of rotation throughout the coin's trajectory," the scientists said.
"According to the Diaconis model, precession causes the coin to spend more time in the air with the initial side facing up.
"Consequently, the coin has a higher chance of landing on the same side as it started."
