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
The Front of a coin is the heads side Known as the obverse. The Back of a coin is the tails side "reverse".
ignoring the minute chance that it will land on it's side as well as assuming that the air resistance due to the different patterns in the coin is negligible the chance of a coin landing heads is 50%
the probability is actually not quite even. It would actually land heads 495 out of 1000 times because the heads side is slightly heavier
The odds that a tossed coin will land tails side down remain one in two no matter how many times the coin has previously been tossed.
