Re: Can someone ask this to the Oracle of Mathematica for me

Well I examined it and it turns out that there are probably no representable solutions to this equation for specific n, and certainly none for general n. That's a shame. Thanks for everyone's assistance.

Re: Can someone ask this to the Oracle of Mathematica for me

My difficulty with these other programs is figuring out how to restrict variable domains before solving the equations. I've reduced my problem to solving (n-4)(n-3)(n-2)p^4(n(np+n-3)-p+10)=8(n-5)p((n-4)p((n-3)p+3)+6)+48 ...

Re: Can someone ask this to the Oracle of Mathematica for me

I don't know the syntax for those programs at all... I suppose I could resort to learning them, but I thought that this wouldn't be any trouble for anyone I could find who already runs Mathematica. Thanks for the suggestion.

Re: Can someone ask this to the Oracle of Mathematica for me

Unfortunately, no. It's just slightly too large for WolframAlpha to want to solve. Damned annoying. EDIT: Actually, that's misleading. Since this is an optimization problem, I have to differentiate that expression. Fully simplified, it's short enough: 1/24 (10 p+5) (1-p)^(n-4) ((n-4) p ((n-3) p ((n-...

I'm trying to solve this thing and other systems I have access to are cumbersome or inadequate. So could someone with access to Mathematica type this in: Maximize[{CDF[BinomialDistribution[n, p], 4] (10 p+5), 0 <= p <= 1}, p] And copypaste the answer back over to me? or take a screen, that would wor...
