So based on our venn diagram, we got m for medical tests.
00:02
78 had medical tests.
00:04
So 78 goes there.
00:05
45, we're seen by a nurse.
00:08
30 was seen by a doctor.
00:11
18 had medical tests and we're seen by a doctor, but not seen by a nurse.
00:16
So 18 is going to be this intersection right here.
00:19
11 were seen by a nurse and have medical tests.
00:22
So 11 is that intersection there, not seen by a doctor.
00:26
Oh, not seen by a doctor.
00:27
No mind.
00:28
18's got to go here and 11's got to go here.
00:30
I forgot about that it wasn't we're excluding seeing the other ones two patients were seen by a doctor without being seen by a nurse and without having medical tests so two patients go right here nine have medical tests and were seen by a doctor and a nurse that is the intersection of all three of these so nine goes right there so finding out all the rest of these values here i'm going to start with medical tests of 78 we're going to subtract the 189 and 11...
