What is the probability of getting $3$ heads in a row? Would it be $\frac 18$?

If you are assuming 3 coin tosses of a fair coin, then there are $2\times 2\times 2=8$ outcomes. Three consective heads can occur only one way. So, yes, the probability is $\frac{1}{8}$
Assuming a fair coin, how many sequences of three throws are there? Are they equally likely? How many of those are "3 heads in a row"?
