Can anyone help me with the function of probability? What
I am trying to do it determine the probability of getting
certain vaules give a list of possibilities.

For example, if Johnny can only carry 3 things in his bag
and his choices of things to carry are 1. notebook 2.
lunchbag 3. laptop 4. palm pilot 5. text books

what are the different possibilities/combinations in
Johnnys bookbag.

I would like for the program to give the answers of
notebook, lunchbag & laptop...etc.
 
Check the macro posted by Myrna Larson on july 25 2000,
you can look for it in the google advanced group search
using keywords "permutation" and "combination", Post title
is: Re:COMBIN. The message was posted in the
microsoft.public.excel.misc newsgroup

=Premut()- will give the # of possible combinations, but I
don't know what will list the items involved.

There are very good reasons not to help the OP. This looks like a homework
problem, and if so the OP really should figure it out on his/her own.

That said, PERMUT does *NOT* give the number of combinations. COMBIN does that.
PERMUT gives the number of permutations. The difference may be illustrated as
follows: {apples,oranges} and {oranges,apples} are the *SAME* for COMBIN (order
doesn't matter) but different for PERMUT (order matters). Neither list any
combination or permutation.
 
Hello Marvin -

problem, and if so the OP really should figure it out on
his/her own.

Then by that standard, this forum may as well shut down.
How many people are at work getting paid for their
knowledge of XL, yet they post here continiously?

They're also asking for help with their "homework".

No, they're asking help with their *work*, not their homework. There's a
difference. The goal of work is to get the work done. The goal of homework
is to make students think for themselves. Obviously this form of instruction
doesn't work for you.

Besides, you asked about how to figure out all the combinations of 3 out of
5 items that could be stored in a bag. Are you really going to claim that
(1) you can't figure this out on your own but (2) believe that you should
get credit for whatever course this is for?
 
Actually, I have experienced qualms about helping some people with
workwork -- people who are the XL 'experts' and need help with very
simple questions, and people who work for corporations that report
multi-billion dollar quarterly profits and want volunteers to develop a
solution from scratch by posting incremental requests.

But, that's a philosophical issue and we are free to disagree on what
is homework, workwork, and freework -- and where one draws the line
between them.

In this case 'disagree' is too strong a term. We reach different conclusions due
to different beliefs. In support of my own (FWLIW), most companies that truly
rely on Excel for anything important either have many people who understand
their Excel models (so if one or another of them ask the occasional question in
ngs, all should be able to figure out the responses) or those companies are
living on borrowed time awaiting the sole knowledgeable user's departure.

If you view Excel as a glorified calculator (which I do - it's a very nice
calculator!), then helping others use their glorified calculators is no big
deal. On the other hand, if you view Excel as a program development platform,
then no one should be allowed to use it until they've mastered binary floating
point and commonly expected software engineering practices such as testing,
revision control, documentation, etc. That'd rule out answering at least half
the questions posed in this ng. So I await half of your responses being nothing
more than textbook recommendations.

As for schoolwork, I'll continue to view it as fundamentally different. I
suppose the distinction is that if I believe the OP could solve the problem with
paper and pencil via brute force, there's no good reason not to show possibly
more efficient ways to solve the problem in Excel. However, if the core of the
post is how to solve the problem and the fact that the OP is trying to solve it
using Excel is secondary, then the question becomes why does the OP need to
figure this out? If the answer is just means to an end such as business reports,
no problem helping them. However, if the answer is the end (which is almost, but
not quite exclusive to coursework), then there's no good reason to give the OP
the answer. ESPECIALLY since the problem has almost certainly been asked AND
answered in one of the Excel ngs before.

You must have been a TA in grad school. There are times you've got to tell
students that they must figure out some problems on their own, and if they just
can't they should reconsider their overall course of study.
