probablity by sudra on 2009-10-21 12:59:05
3.a book 1000 pages was scanned and the number of printing errors in each page was noted .the distribution of number of error in a page was found to be “poision” .if there were exactly 301 pages free from error and 26 pages with exactly 4 error each,estimate the average error per page.

Also estimate:

a) I) The number of pages with exactly “1” error and
ii) The number of pages with exactly “2” error s

b) If for the 2nd edition of the same book (published after 3 years), the average error s per page with “1” estimate.
i) the number of pages with “0” error .
ii) the number of pages with exactly “1” error.

Given that: e-=0.36788
