That is still a mystery,my friend.
Dear friend ,I hope you haven't asked this question to anyone else.Please let it remain the same way.....
Probability of getting head (H) =1/2
P(H) - 2=P(H)-2x1=P(-) =1/2-2=-3/2--- Eq. 1
P(getting a tail (T)) =P(T) =1/2--- Eq. 2
Eq.2-Eq.1=P(T) - P(-) = P(l)
The thin line between the brackets represent the thin edge of the coin. So P(l) = P(T) - P(-) =1/2-(-3/2)=2
As it is greater than 1 it is impossiple to make a coin stand on its edge
Nearly 70% of all the dictators does not know English. So they is no point in these beard headed muddle heads conducting dictations
Go directly to Welburn Street. Just after the police station, there is a sharp right turn. Just beside that road there is a public toilet. Inside the toilet there is a well furnished closet.
