00:01
All right, so we have a good contingency table here.
00:05
So let's see what we got.
00:10
So we looked at, did just some surveys at looking at party affiliation and whether or not the earth is warming.
00:18
So is, or believing the earth is warming and being a liberal democrat, mutually exclusive.
00:27
It doesn't look like it because you can be a liberal democrat and not believe in global warming.
00:34
If it was mutually exclusive, there would be nothing.
00:39
It's like, no, you could be either this or that.
00:42
So no.
00:43
The probability that a respondent believes the earth is warming or a liberal democrat.
00:49
So let's see, look at the warming.
00:50
So here are the people that believe the earth is warming, which ends up being 0 .6.
01:00
Or a liberal democrat.
01:01
Liberal democrats here.
01:04
So you could also be this.
01:07
0 .01 and don't know 0 .01.
01:10
So you could be here or these two.
01:15
So it's 0 .6 plus 0 .02 .62.
01:29
Because that's if you randomly picked one person out of the study, they're 60 % who believe the earth is warming and then a democrat, liberal democrat is 0 .8 plus 0 .01 plus 1 .1.
01:46
0 .01, so 0 .2.
01:48
But you have to account that it's all these plus this.
01:54
It's like just go around the table.
01:56
Where are you counting up? so it's that? what's the probability that a chosen respondent believes the earth is warming, given their liberal democrat.
02:09
So given their liberal democrat, liberal democrats here, so 0 .2, the probability that they believe the earth is warming, given a liberal democrat, is point two is 0 .18 divided by 0 .2 because you have 0 .2 liberal democrats or proportion wise and 0 .18 of them are that proportion is uh is uh believes you have this warming so 0 .18 divided by 2 .9 .0 .9.
03:09
Which i guess i'm looking at i could have seen that but it's okay.
03:16
Let's see.
03:17
What's the probability that a randomly chosen participant? believe earth is warming, given they're a republican.
03:24
Say, given their republican.
03:27
So this doesn't...
03:28
Oh, conservative republican...
