and the denominator of the probability fraction is .
Thus the probability of a coin landing heads is , which is the same as saying that a coin lands heads % of the time.
What is the probability of the coin landing tails? We can do the same analysis as for the coin landing heads, finding a probability of , or, knowing that if a coin doesn't land heads it has to land tails, and understanding that of the MUST be equal to , subtract:
the probability of a coin landing tails must be .
In this case, (a 1/2 chance of landing either heads or tails) remain ; NO MATTER HOW MANY TIMES you flip a coin, time the coin is EQUALLY likely to fall or .
