You're gonna get a four-cylinder engine, or you're going to get a six-cylinder engine. Now, if you got a four-cylinder engine, you're either going to get red, blue, blue, green, green, or white, or white. And if you got a six-cylinder engine, once again, you're either going to get red, blue, I think you see where this is going, that's not blue, red, blue, blue, green, green, or white, or white. 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.
