Re: Glamor Geometric Series

Consider that the 4th person chose dish X.

The Probability that the 1st Person chose dish X is 1/5.
The Probability that the 2nd Person chose dish X is 1/5.
The Probability that the 3rd Person chose dish X is 1/5.
Therefore, the probability that anyone has chosen X before is 3/5.

So, the possibility that the dish is previously not chosen is 2/5

Re: Glamor Geometric Series

Is that the exact question?


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: Glamor Geometric Series

I would say yes, because the answer you gave me works

That method is faulty.  If there were 5 people before D, you would end up with 5/5 and no chance for D.

I'll work on an analytic method.

Re: Glamor Geometric Series

Must be different for me and you then. Mine requests a + b in a / b.

Ya,  so... What to do? sad roll

Hi bobbym,

They ask me for a + b too

You can not add them up.

Re: Glamor Geometric Series

hi

I get that too by my own method and a general formula too.  smile
