Answer:

1/8

Explanation:

The probability that you will get heads on any coin flip is 1/2, meaning half of the time you will get heads. The probability of this happening to you twice in a row is 1/2*1/2, as you have a probability of 1/2 of getting heads on each flip. This means the probability of getting three heads in a row is 1/2*1/2*1/2=1/8
