If the results of a movie survey and the types of movies were comedy, drama, and science fiction, whenever possible, i want to work at this innermost region that i'm highlighting.
00:19
That region represents the people who responded and said they liked all three types of movies.
00:27
For this problem, i'm told that there are six people who like comedy, drama, and science fiction.
00:35
Now, 13 people like comedies and drama.
00:39
Comedies and drama is this oval that i'm highlighting in green.
00:45
That's the intersection of the two topics, comedy and drama.
00:51
There's 13 people in that green area, but i already have six people in there.
00:57
So i need to subtract that six from 13, and that will give me seven for my remaining.
01:06
10 people like comedies and science fiction.
01:10
That means this is a four because six are already there.
01:16
11 people like dramas and science fiction.
01:20
This number is a five.
01:23
Now i'm going to go to my single region.
01:26
26 people like comedy...
