Okay, so looking at the venn diagram, how many sets are involved? it says using the venn diagram, answer the given questions to the given questions to follow mr.
00:14
Ballot present.
00:14
Mr.
00:15
Ballot presented a diagram showing his student's favorite board games.
00:19
Each board game is represented by the letter c, s, or d.
00:41
So there's three sets.
00:43
There's chess, scrabble, and d.
00:48
So we're going to go with three sets.
01:02
Four, because there's the universal.
01:04
You've got to count for the eight.
01:05
So let's go with four.
01:08
How many like chess only? so chess only is only, it's in no overlap.
01:16
So chess only is 10.
01:18
Scrabble only is where it's s in no overlap.
01:24
So that's 18.
01:26
Demath only would be 17.
01:34
Like both chest and scrabble so here is chest here is chess here is scrabble and you want to know where they overlap so 16 and 6 so that's 26 like scrabble and demath here is demath here is scrabble so that overlap so that overlap so that overlap so that overlap here six plus 21 is 27 here is chess here is demath so five plus six is 11 how many like all three all three is in this overlap piece right here in the very center which is six like all three how many do not like any of those three that's out here eight how many students are there in all so we just need to add all those numbers up so 10 plus 16 plus 18 plus 21 plus 6 plus 5 plus 17 plus 8 1001.
03:33
All right, so the universal set is everyone.
03:36
So it's everybody inside the box.
03:41
Use the end diagram of it.
03:42
It's the universal set is everybody.
03:45
So that's everybody inside of it.
03:49
So i'm just going to put everyone because i'm not going to have enough room to list everything...
