And then how many total outcomes? Well, that's 2 times 2, because I've got 2 in the first, 2 in the second flip. And then essentially, we multiply 2 times the number of flips. So that's 5, 6, 7, 8. And that equals 2 to the 8th. So the number of outcomes is just going to be 2 to the total number of flips. And hopefully that makes sense to you.
