One side of a coin usually has a "head" of someone. The other side is the tail.
The probability of a coin landing head-side down is 0.5 The probability of landing head-side up is 0.5 Did you mean to ask the probability of it landing on its edge ?
The side of a coin displaying a head is called the obverse. It typically features the portrait of a prominent figure or symbol associated with the issuing authority.
The probability of the coin landing "head" side up is 50/50, meaning it could land "head" side up or "tail" side up. The odds of any single coin flip are always the same, no matter what happened on the previous tosses -- provided the coin is not a "double-head" (or "double-tail") "trick" coin
It's a coin, because it can flip on the head or the tail's side. The only 6-letter coin is a NICKEL.
