We will just keep looking at people, I guess we could say, over multiple days, forever. It will work for an infinite number of years, just for the sake of this problem, until an SUV actually shows up. Try to figure this out. I'm assuming you've had a go. Some of you might say, well, isn't this going to be equal to the probability that V is equal to five plus the probability that V is equal to six plus the probability that V is equal to seven, and it just goes on and on and on forever. This is actually true. You say, well, how do I calculate this?
