Mr.Fantastic.....can you pls tell me how to solve the above problems using formulae......rather than anything which is complicated.....that would be helpful....I've seen this questions and started working on it.....instead I thought I'll find out from the experts if there are any formulae for such kind of problems.........I've started learning maths recently.......pls help.
You have been given three suggestions. Using the binomial distribution is the closest to a formula that you get. Yuo replied within 10 minutes of my last post. I don't see how that could be nearly enough time to try and do as I suggested. Read this: http://72.14.235.132/search?q=cache:...&ct=clnk&gl=au
Or this:
