So if you can make that assumption, you could say that the probability of getting heads and heads, or heads and then heads, is going to be the same thing as the probability of getting heads on the first flip times the probability of getting heads on the second flip. We know the probability of getting heads on the first flip is one-half, and the probability of getting heads on the second flip is one-half. And so we have one-half times one-half, which is equal to 1 4th, which is exactly what we got when we tried out all of the different scenarios, all of the equally likely possibilities. Let's take it up another notch. Let's figure out the probability, and we've kind of been ignoring tails, so let's pay some attention to tails. The probability of getting tails and then heads and then tails, so this exact series of events. So I'm not saying in any order, two tails and a head.
