If you flip three fair coins, what is the probability that the first two flips will both be heads, and the third flip will be either heads or tails?

Question

I have been trying to solve this for hours, but I still can't even find help that will help me enough to where I can at least know what to do and figure out the question on my own.

Answer 1

The easiest way to see this is to write down all 8 possible results.

Once you write down all the possibilities it will be obvious that the probability you want is 1/4
