What is the probability of getting a tail and then two heads flipping a fair coin three times.

you flip the coin 3 times.
the probability of getting a tail on the first toss is 1/2..
the probability of getting a head on the second toss is 1/2.
the probability of getting a head on the third toss is 1/2.
the probability of getting a tail on the first toss and a head on the second toss and a head on the third toss is 1/2 * 1/2 * 1/2.
that would be equal to 1/8.
the possible combinations are:
HHH
HHT
HTH
HTT
TTT
TTH
THT
THH *****
H represents head.
T represents tail.
there are 8 possible combinations.
only 1 of them is THH.
THH means tail on the first toss and heads on the second and third toss.
