And in your 50 visits, you don't see more than, you never see more than two people in line. I guess this is a very efficient cashier at this frozen yogurt store. So based on this, based on what you have observed, what would be your estimate of the probability of finding no people in line, one people in line, or two people in line, at 4 p.m. on the days after school that you visit the frozen yogurt store? And you'll say you only visited on weekdays where there are school days. So what's the probability of there being no line, a one person line, or a two person line when you visit at 4 p.m. on a school day? Well, all you can do is estimate the true probability, the true theoretical probability. We don't know what that is, but you've done 50 observations here, right?
