And once again, we can do that by looking at the relative frequency. The relative frequency of zero, well, we observe that 24 times out of 50, and so 24 out of 50 is the same thing as 0.48, or you could even say that this is 48%. Now, what's the relative frequency of seeing one person in line? Well, you observe that 18 out of the 50 visits, 18 out of the 50 visits, that would be a relative frequency, 18 divided by 50 is 0.36, which is 36% of your visits. And then finally, the relative frequency of seeing a two-person line, that was eight out of the 50 visits, and so that is 0.16, and that is equal to 16% of the visits. And so there's interesting things here. Remember, these are estimates of the probability.
