So how many possible outcomes are there? Well, you could just count, you could kind of say the leaves of this tree diagram. One, two, three, four, five, six, seven, eight possible outcomes, and that makes sense. You have two possible engines times four possible colors, two times four, and you see that right here, one group of four, two groups of four. So this outcome right here is a four-cylinder blue car. And this outcome over here is a six-cylinder green car. So there's eight equally possible outcomes, and which outcome matches the one that we, I guess, are hoping for, the white six-cylinder car?
