### What is the probability of exactly three heads in four flips of a coin given at least two are heads?

If you know that two of the four are already heads, then all you need to find is the probability of exactly one heads in the last two flips. Number of possible outcomes of one flip of one coin = 2 Number of possible outcomes in two flips = 4 Number of the four outcomes that include a single heads = 2.
