If you toss a coin in the air and the first 9 times it lands on heads what is the probability it will land on tails the tenth toss?
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.
