# probablity

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 â€œpoisionâ€ .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 â€œ1â€ error and
ii) The number of pages with exactly â€œ2â€ error s

b) If for the 2nd edition of the same book (published after 3 years), the average error s per page with â€œ1â€ estimate.
i) the number of pages with â€œ0â€ error .
ii) the number of pages with exactly â€œ1â€ error.

Given that: e-=0.36788

Good day.

As a rule, we don't do other people's homework.
Also, this section is meant for asking help about using PlanetMath, and not about doing exercises.

If you are stuck at some point of your work on the exercises, you may ask for help in one of the appropriate sections, e.g., "General Questions - University/Tertiary", and explain your difficulties in detail.

This also applies to your other recent posts.

Best regards,
