So here we have this question with n is equal to 105 people.
00:04
Let's split them up between working age and not working age.
00:11
So most of these people are going to be working age, right? so i immediately know that i have 26 people who are under 16.
00:18
Those are people who are not of working age by definition.
00:21
But now we have 25 full time, right? those people, i presume, are working age because they're working.
00:29
We have 13 part -time, again, presumably these people are working age.
00:35
We have 10 retirees, again, they are working age.
00:39
We have five homemakers, again, presumably working age, homemakers, they don't want a job, 12 students, and three disabled.
00:56
So how many does that leave? well, if i add all those up, i get 25 and 13 is 13...
