Hi, i'm david and i'm here to help you answer your question.
00:04
Let me bring up your question here.
00:07
In this question we discuss about the poisson distribution.
00:10
Let me remind you that it will have the x followed by the poisson with the rate equal to the lambda and then the proper ptl x equal to k, it will equal to the e power minus lambda, lambda power k, over k factorial.
00:29
Now here we are given the that x equal to the number of the error on one page.
00:40
So we see x it will follow by the possum with the rate equal to lambda equal to the 0 .2 error per page.
00:55
And now the question is going to find the probability that an article of the 10 pages.
01:01
So we know that one page, the number of the error, it will be 0 .2 error.
01:10
And if we have the 10 pages, the error here will equal to the 0 .2 times 10, so equal to two errors.
01:21
And this will be the rate equal to the two errors on the 10 pages.
01:30
Therefore, i want to find the probability in the part of the page.
01:34
That there will be no error.
01:37
So if we call x will be the number of the row in 10 pages, so x will be equal to the 0...
