each trial is separate, the chance of getting a tail on the first try is 1/2
on the second try it is 1/2
on the third try it is 1/2
so if this happens in all 3 trials, you get 1/2 x 1/2x1/2 = 1/8
another way to look at this is to write out all possible combinations of events, H will mean heads and T tails
you could have:
H H H meaning all three heads
H H T first two are heads, the third tails
H T T
H T H
T H H
T T H
T H T
T T T
you can see that there are 8 possible outcomes of flipping a coin 3 times; only one of the 8 results in all three Ts
