We're in a pie diagram, and we want to find some probabilities from that pie diagram.
00:05
We want to find the probability, if we randomly choose a person, that the person is at least 15 years old.
00:14
And if we look at that, there are a lot of wedges, but if you look at there are two wedges that are not included.
00:22
And one of the categories is under five, and that is 7%.
00:30
And another of the categories is from 5 to 14.
00:35
And that category is 13%.
00:38
So we could go around and add up all of those other wedges, and that would give us our answer.
00:44
But it's actually easier to find what we don't want.
00:48
So if we find one minus the probability of what we don't want, which is somebody who is less than 15 years old, we can actually get that answer more easily.
00:59
So the probability, and i'll put it in terms of, we'll do it in terms of percent...
