No, I am hoping to get a good sleep instead.

What is your favorite question of the type 'What is your favorite x'?

What is wrong with my quote?

I can't get it to work

#4 Re: Help Me ! » Permutation Problems » Today 06:20:11

Copied where?

What is your GF?

Does that GF work?

What is p5 and how are you doing?

I do not understand the gf

#11 Re: Help Me ! » Permutation Problems » 2014-09-15 05:15:51

I do not know how a CAS finds the coefficient of the terms.

#12 Re: Help Me ! » Permutation Problems » 2014-09-15 05:07:21

I understand  the rest. I hope I will be able to explain it to Sa tommorrow.

#13 Re: Help Me ! » Permutation Problems » 2014-09-15 04:58:52

It is 18 but what is wrong with post 45?

#15 Re: Help Me ! » Permutation Problems » 2014-09-15 04:45:40

For two pairs, you have two select the two kinds whose pairs are taken. There are binomial(3,2) ways to do that and then with the same reasoning you multiply with 4! An divide with 2! And 2!

#16 Re: Help Me ! » Permutation Problems » 2014-09-15 04:43:53

Oh, sorry. Now I multiply 4! In the denominator to get all the possible arrangements and divide by 2! Because there is one repeatition.

Please explain me the two pairs.

#18 Re: Help Me ! » Permutation Problems » 2014-09-15 04:11:39

A pair of kabooblydoos, a pair of transparent soaps and a pair of carrots.

#19 Re: Help Me ! » Permutation Problems » 2014-09-15 04:07:16

Yes, but how did you get that expression?

#20 Re: Help Me ! » Permutation Problems » 2014-09-15 03:04:17

Would you please explain the casework? I do not get what you mean by 1 pair and etc

#21 Re: Help Me ! » Permutation Problems » 2014-09-15 02:59:36

I have never seen you talking about Tucker and gfology is very hard unless I have a good foundation of gf's.

#23 Re: Help Me ! » Permutation Problems » 2014-09-15 02:05:11

How can I take those courses?

#24 Re: Help Me ! » Permutation Problems » 2014-09-15 01:56:54

That will take too much time.

#25 Re: Help Me ! » Permutation Problems » 2014-09-15 01:44:26

How do I get the coefficient of x^4 from that gf without using a CAS?
