Hi, i'm david and i'm here to help you answer your question.
00:03
Now let me bring up your question here.
00:06
In the question here we are going to discuss about the binomial distribution.
00:10
Let me remind you that even the x that followed by the binomial when the n and the p, then the probability of x equal to k, equal to n, 2x, p, b, k times 1 minus p b b b.
00:25
In this question here, we are given that the probability that the component operating successfully equal to the 0 .9.
00:33
So we have the p equal to the 07.
00:36
We have the symbol n equal to the 4 component.
00:39
And it will define the x that will equal to the number of the component that operates successfully.
01:05
And then we see that x here will follow by the binomial with the n equal to the 4.
01:11
And p equal to the 0 .9.
01:13
Now in the first question a, once you find the probability that the system will function properly, and the function and the system will function as long as one of the component is operational.
01:31
So means i want to find the probability that x will be equal to 1.
01:35
This will be easy to consider the 1 minus probability of the x equal to the 0...
