All right, we're giving a whole bunch of information about people that like football, baseball, and or hockey, all right, and we're asked a couple of questions based upon that.
00:14
So with this, i drew a venn diagram here with my three overlapping circles because certainly they overlap.
00:19
Some people like football, baseball, and hockey, all right, but some like only football, some like any of the combinations.
00:26
All right.
00:26
So let's go through and start filling in our diagram here.
00:30
All right.
00:30
So it told us the easiest thing is 12 like none of them.
00:33
I'm just going to put that 12 outside.
00:35
They don't fall into any of the categories there.
00:37
The next place to go to is 10 that like all three.
00:40
That's the overlap.
00:41
The overlap is only this one little middle section here.
00:44
So i'm going to put that in next.
00:45
And that's pretty simple to find.
00:47
Those two numbers go in directly.
00:49
From there, we have to start doing some subtractions.
00:52
Because it tells us that 15, like baseball and hockey.
00:54
Baseball and hockey overlap in these two circles here.
00:57
All right.
00:58
We need this to be 15.
01:00
Well, 10 of them are there.
01:01
That means i need another five.
01:02
Now i've got my 15 that like both baseball and hockey.
01:07
21 like football and hockey.
01:09
All right.
01:09
Well, again, football and hockey overlap here.
01:12
I have 10 of them in the center, so i need 11 more so i can get 21 total.
01:17
Last but not least was 18 like football and baseball.
01:20
Football and baseball is these two sections up here.
01:23
I had 10 in the middle.
01:24
So then i get eight for that one up there.
01:28
Let me rewrite that a little bit more neatly so we can make sure and see exactly what these numbers.
01:32
Represent.
01:33
All right.
01:34
So there's eight up there.
01:36
All right.
01:37
Now, the last part's going to take a little bit more subtraction even.
01:40
I know 92 liked football.
01:41
Well, i've got this full circle liking football...
