some this problem we've bred to Hampshire's with the capital
2
00:00:05.019 --> 00:00:09.580 A:middle L:90%
B lower case be Gino type and were given two
3
00:00:09.580 --> 00:00:12.699 A:middle L:90%
questions. One. What's the probability that black fur
4
00:00:12.839 --> 00:00:15.230 A:middle L:90%
and two given that they have black for what is
5
00:00:15.230 --> 00:00:18.179 A:middle L:90%
the probability that there Gino type is Capital B lower
6
00:00:18.179 --> 00:00:22.899 A:middle L:90%
case. Be part, eh? We're gonna use
7
00:00:23.170 --> 00:00:27.070 A:middle L:90%
our definition of probability successful outcomes over total outcomes.
8
00:00:27.219 --> 00:00:30.350 A:middle L:90%
Now of these forge of these four possible Gino types
9
00:00:30.879 --> 00:00:33.079 A:middle L:90%
, this one will be black. This one will
10
00:00:33.079 --> 00:00:36.179 A:middle L:90%
be black and this one will be black, which
11
00:00:36.179 --> 00:00:40.460 A:middle L:90%
means a probability at a three out of four possible
12
00:00:40.460 --> 00:00:42.950 A:middle L:90%
options. Three successes. So we get 3/4 of
13
00:00:42.960 --> 00:00:50.000 A:middle L:90%
0.75 We're part B. We'll just use base there
14
00:00:50.229 --> 00:00:59.649 A:middle L:90%
. So this will be probability having black fur given
15
00:01:00.539 --> 00:01:07.930 A:middle L:90%
that Gina type times the probability of having that Gino
16
00:01:07.930 --> 00:01:17.819 A:middle L:90%
type all over probability. Having black fur. All
17
00:01:17.819 --> 00:01:21.560 A:middle L:90%
right. Knowing that let's plug in some numbers the
18
00:01:21.560 --> 00:01:25.129 A:middle L:90%
probability of having black for given that your Gina type
19
00:01:25.140 --> 00:01:26.420 A:middle L:90%
is Capital B. Lower case be is one.
20
00:01:26.750 --> 00:01:30.650 A:middle L:90%
That's how it works. The probability of having that
21
00:01:32.450 --> 00:01:34.700 A:middle L:90%
that Gino type is 1/2 because these two are treated
22
00:01:34.700 --> 00:01:42.069 A:middle L:90%
as the same. We divide this by the probability
23
00:01:42.069 --> 00:01:46.370 A:middle L:90%
of having black fur, which is 3/4 and this
24
00:01:46.379 --> 00:01:53.849 A:middle L:90%
ends up being 2/3 0.6 67 ish.
