I'm going to draw a venn diagram to help organize the data here.
00:04
And we have breakfast, lunch, and dinner.
00:06
And i'm going to start at the bottom.
00:08
It says, where it says 58 students ate all three meals.
00:11
So 58 is going to go in this region because it's in all three circles.
00:16
90 students had lunch and dinner.
00:19
So lunch and dinner would be right here.
00:22
There's 90 students that go in that region, but we already have 58.
00:26
So that means that we're going to have another 32 here.
00:30
Then we have 112 ate breakfast and dinner.
00:34
So we have, here's our breakfast and dinner.
00:37
We have 112 of those.
00:39
Again, we already have 58, so that's going to be 54 that need to go in this region.
00:45
Moving up, 68 ate breakfast and lunch.
00:49
So that's going to be here.
00:52
68 go in that region, but i've already got 58.
00:55
That means we need to put 10 here.
00:57
Now let's move up to 271.
01:01
Students ate dinner.
01:03
That's going to be this entire circle here, 275, but we need to get rid of the 54, the 32, and the 58, because they're already in the circle.
01:16
So this can be 90, 140, 144.
01:19
So it's going to be one, three, one, so 131, we go in this region.
01:24
Let's do the same thing for lunch...
