For this problem, to begin, let's set up our contingency table to understand what it's saying.
00:07
So we have d, not d, c, and not c.
00:13
Gotta be careful about how you say that.
00:17
So we can see that for c and d, we have 12, for c and not d, we have 18.
00:25
Now, one thing that i'll include here is that we'll actually want to have totals, a total row and a total column for what we'll be working on here.
00:39
So we can see that the total for c would be 30.
00:44
For not c, we have 24, 26, so the total for not c would be 50.
00:55
So the overall total is going to be 80.
01:00
For d, we have 12 and 24, so that would be 36.
01:08
And for not d, we have 18 plus 26, so that is going to be 44...
