<v Instructor>Hello students.</v>

2
00:00:03.300 --> 00:00:08.300
Now we are here with 2 D.

3
00:00:08.970 --> 00:00:11.940
And the D is asking us what is the probability

4
00:00:11.940 --> 00:00:14.190
that a child is hyperlipidemic

5
00:00:14.190 --> 00:00:16.620
if both parents are hyperlipidemic?

6
00:00:16.620 --> 00:00:19.170
So the problem here has conditions attached

7
00:00:19.170 --> 00:00:22.170
to both the numerator and the denominator.

8
00:00:22.170 --> 00:00:23.370
And here we are looking

9
00:00:23.370 --> 00:00:26.430
for both parents being hyperlipidemic.

10
00:00:26.430 --> 00:00:29.040
So given that you probably have figured we are going

11
00:00:29.040 --> 00:00:33.333
to be focusing on the first column, and again,

12
00:00:33.333 --> 00:00:36.120
I'm going to use a different color so it's easy

13
00:00:36.120 --> 00:00:38.635
for us to understand what's going on.

14
00:00:38.635 --> 00:00:43.050
Why don't I use blue this time?

15
00:00:43.050 --> 00:00:47.459
So here the numerator is going to be 45

16
00:00:47.459 --> 00:00:52.459
because we are looking for children who are hyperlipidemic.

17
00:00:52.590 --> 00:00:56.560
So the numerator is 45 and then we are looking

18
00:01:00.660 --> 00:01:05.660
for the denominator where basically both parents

19
00:01:06.030 --> 00:01:07.590
are hyperlipidemic.

20
00:01:07.590 --> 00:01:12.510
So that, as you can see, is going to be, again, 58.

21
00:01:12.510 --> 00:01:15.000
But I'm going to again, use a different color

22
00:01:15.000 --> 00:01:17.643
so we can see this nicely.

23
00:01:19.830 --> 00:01:22.623
So this is going to be our denominator.

24
00:01:30.390 --> 00:01:31.753
That's going to be 58.

25
00:01:32.790 --> 00:01:37.790
So now let's write the problem and see how we are going

26
00:01:38.190 --> 00:01:39.033
to solve it.

27
00:01:44.460 --> 00:01:48.490
So the problem here is going to be the probability

28
00:01:50.337 --> 00:01:53.100
that the child is hyperlipidemic

29
00:01:55.003 --> 00:01:57.253
(no audio)

30
00:02:06.510 --> 00:02:08.080
if both parents

31
00:02:14.831 --> 00:02:17.003
are hyperlipidemic.

32
00:02:18.706 --> 00:02:20.956
(no audio)

33
00:02:28.620 --> 00:02:32.790
So that will be 45 divided by 58.

34
00:02:32.790 --> 00:02:35.103
And when we do that division,

35
00:02:37.320 --> 00:02:41.223
what we get is 0.776, which is 77.6%.

36
00:02:48.960 --> 00:02:50.610
So basically what does that mean?

37
00:02:50.610 --> 00:02:55.610
That means that there is a 77.6% probability

38
00:02:56.070 --> 00:02:58.260
that a child is hyperlipidemic

39
00:02:58.260 --> 00:03:00.653
if both parents are hyperlipidemic.
