So from the question, the probability that the employees would lay up their bosses, so i say p, that's 32%.
00:13
So it can say 0 .32.
00:18
The sample size, n is 10.
00:22
So from the given information, this distribution is binomially distributed n &p.
00:32
So now let's look at the first part of the question.
00:36
Before that, so for nominal distribution, probability that it was supposed to.
00:42
X is given by n times to the x times q to the n minus x.
00:51
So here q is 1 minus p.
00:55
And it's 1 minus 0 .32.
01:00
That's going to be 0 .68.
01:08
Unless you've got the first part of the impression.
01:12
I'm going to find the probability that is exactly 3.
01:20
That is just equal to 10 combination 3.
01:26
10 termination 3 times p is 0 .322 times 2 is 0 .6 8.
01:38
Exponent n minus x plus 10 minus 3 which is 7.
01:44
So if you crumb this out you get a c.
01:51
We get 0 .264 5 .7.
02:05
Okay.
02:07
We can round this up to 4 decimal places that 0 .2644.
02:15
The next one is the probability at most 3.
02:24
That is just parameter x .6 .0, then 2, and then 3.
02:35
So we just need to do the substations about it.
02:49
So we'll see.
02:52
So for x equals 0, 10 combination 0 times 0 .3 2, 0 .60, 0 .6, exponent n minus x is 10 minus 0 by just 10.
03:10
So that's what x equals 0 plus...
