1 / 2
A coin has 1 / 2 chance to fall on his head and 1 / 2 chance to fall on his
back BUT
if you make series and constantly
predict the opposite of the predicing throw gives 1 / 2 chance of a right
prediction in contrary of predicting the same constantly what gives a chance
<1/2 .
The formula for the chance of equal heads and backs is
p (n ) = n! / ( (n / 2 )! * ( n / 2 )! * 2^n )
with n the number of throws
