The probability of getting exactly k successes in n trials is ... use your figures! EDIT: Oh, a little help: . eg 3!=3x2x1 It's getting late here

[quote user="Puncher"]If I throw it twice then chance of my number coming up in any of the throws is 1/6 + 1/6 = 2/6 = 1/3.[/quote] I found for you (and Soundproof): The probability of an event can be expressed as a binomial probability if its outcomes can be broken down into two probabilities p and q , where p and q are complementary (i.e

[quote user="soundproof"] I'd love for Tournedos and saf to take us through their reasoning in a detailed manner, but I do not see why not winning should have any relevance. [/quote] The easiest way to calculate the probability of winning "at least one prize" is to calculate the probability of winning no prizes at all, and subtract

[quote user="Peter "] The raffle ticket analogy is not accurate as as well as the winning ticket being removed, so are the 549 losing tickets for each prize. all you are doing is using big numbers to confuse the issue! [/quote] Actually, in this case (in the calculation) the tickets are "returned back"! I agree though that if they

What about - to check the result - a simple analogy with a local raffle draw? 10 prize draws, 12 times a year, 550 members, all being random, makes it like a raffle draw affair where: there are 66 000 tickets ... 10x12x550 120 per member 120 prizes So chances of not winning anything in each prize draw are: (66 000-120)/66000=0,9982 and there are 120

[quote user="tournedos"]Of course, the real probability for winning at least one prize is larger, because you are not excluded once you have already won.[/quote] But let's perhaps wish this probability will actually decrease - if not, it would mean that the no. of gold members is not increasing (enough)! Of course, Lee could always attempt

Thanks everyone for help - CAROLPA YOU'RE A STAR! Thanks, N.MUSIC is up and running again... I only deleted one file: BeoMediaDatabase.beo

[quote user="Carolpa"] Saf, Did you to reinstall/repair the Beoport software? (download and just rerun the setup) otherwise delete the database located in Documet and Settings; <your account>; Application Data; BeoMediaDatabase; (delete alse the Backups!) than start N.Music. [/quote] Hi Carolpa, Yes, I did reistall/repair for BeoPort

I run avast! and had never any problems so far.

plus finally
