More discrete mathematics questions1) suppose you have 70 books (35 novels, 20 history books and 15 math books). Assume that all 70 books are different #2 20121204 23:58:21
Re: More discrete mathematics questionsHi Jhua4; 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. #5 20121205 00:08:54

Re: More discrete mathematics questionsHi; which is confirmed by direct computation. 4) Is correct. Just a standard Mississippi problem. 5) Please state what you mean by the LaPlace's probability model. In mathematics, you don't understand things. You just get used to them.

Re: More discrete mathematics questions
How do you solve #3??? I cannot find that anywhere... I am sure it is simple, but I cant get it! that is supposed to be +...+6^(n1)  looks like the math script is a bit broken This is not homework  it is a problem on a previous test.. I can't figure it out. I am guessing Jhua4 is from UCI as well, Dillenc0urt? THANK YOU! #10 20121212 19:12:06
Re: More discrete mathematics questionshi PeterG The question needs the binomial formula: http://www.mathsisfun.com/algebra/binomialtheorem.html Using that formula try putting a = 1, b = 6 Notation: Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #11 20121213 04:56:07

so how does it get to I must be missing a step: #12 20121213 05:01:08

Re: More discrete mathematics questions
Yes, #14 20121213 07:15:41
Re: More discrete mathematics questions
Wth... You know this is a trick question, expanding and what not... wth  like a couple hours on that complete nonsense!!! #15 20121213 07:20:08
Re: More discrete mathematics questionsOK. Like this: No 'a's appear in the question you had so put a = 1 and all the a powers are just 1. Put b = 6. And that's it because the LHS is 7^n and the RHS is what you were asked to simplify. Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei
