Each toss of the coin is independent of any other toss......the next toss has a 1/2 probability of being a head or tails

The probability of getting a tails on the tenth toss is 1/2. Previous results do not have any effect on future tosses. For the tenth toss, the odds are 1 out of 2 possible choices. The answer is significantly different if you ask what are the odds of tossing heads 10 times in a row.
