Hello.
00:03
So this question is going to follow a hyper geometric distribution.
00:09
Okay.
00:11
So we're going to say variable x going to be a random variable having a hypergeometric distribution.
00:22
And from the question we could have m to be 4, n to be 6 that is 4 plus 2, and is 3 then k is 2 so the distribution each of k so this is the hyperdrametric distribution that is given by and k and combination k are provided by so if you look in the question you will see that m is representing the four duct tests and the uppercase m is representing the total total, that's four doctors and two nurses.
01:54
That looks at 6.
01:56
N is 3.
01:57
That is what we select.
01:58
That's the random, i mean the size of the committee.
02:05
That's the lowercase n.
02:07
Yeah.
02:07
And then k is going to be the number of nurses.
02:11
So once you have that, this is going to be the formula for the hypergometric distribution.
02:19
So now we're looking for the probability of 2, let's not equal to x let's add 3.
02:37
So this is going to be the same as the summation...
