if a fair coin is tossed 8 times and heads comes up all 8 times, what is the probability that tails will cime up on the 9th toss??

1/2
The ninth toss has absolutely nothing to do with any of the tosses before it.

Event is independent of previous events Therefore, the probablility of tail (or head) is always 50% for any one toss.

Slightly less than 50%, because there's a small chance it might land on its side, like in that twilight zone episode.

it is 1/2 as it is not dependent on previous once

Most likely. Your luck runs out eventually!
