If you flip a fair coin four times, what is the probability of flipping at least three heads in a row? Express your answer as a common fraction.

There are $$2^4$$ ways of flipping the coins.

There are 3 ways to get at least 3 heads in a row: THHH or HHHT or HHHH

Thus, the probability is $$\color{brown}\boxed{3 \over 16}$$

ig my name is cphill now ¯\_(ツ)_/¯
