Total number of possible outcomes = 2 ( that is, head or tail)
P(tail) = 1/2
Each toss is independent of the one before.
So the probability of the 5th throw of getting a tail is still:
P(tail) = 1/2
Answer: 1/2

Total number of possible outcomes = 2 ( that is, head or tail), P(tail) = ½.
Each toss is independent of the one before.
So the probability of the 5th throw of getting a tail is still: P(tail) = ½.
The probability of tail can be measured by taking fifth time around one before and evaluate it.
