This one is feeling pretty straightforward. What's the probability that for each customer she goes to that they're not an SUV? That's one minus 12% or 88% or 0.88. If we want to know the probability that the first four cars are not SUVs, that's 0.88 to the fourth power. That's all we have to calculate. Let's get our calculator out. I'm going to get 0.88, and I'm going to raise it to the fourth power.
