In this question, we're looking at odds of getting collateral, oh, sorry, colorectal cancer.
00:08
And so starting off with just the odds of the cancer in a group with high levels of meat consumption, we're only looking at high levels of meat consumption, so that is this row here.
00:20
Total, we have 250 people in the study that have high levels of meat consumption, and the number that got cancer is 100.
00:32
So that is 100 divided by 250.
00:35
So just type that in your calculator.
00:37
You get 0 .4, so that's about 40%.
00:40
That's pretty high.
00:43
That is the odds of getting cancer with high level of meat consumption.
00:51
Now we want to do the same thing, but with low levels of meat consumption, and you're going to find that, i think, probably a lot lower.
00:58
We'll see, though.
01:00
25 over 125.
01:02
So just do 25 divided by 125, and that is 0 .2.
01:15
So that's actually half the probability of the first.
01:22
So in this chart, we have two columns, right? cancer and no cancer...
