Ok I think I got it now. I tried to get back to me homework but I couldn't lol

Anyways, the Probability of choosing a normal coin is (572/573) and then the probablity of getting all heads with them is (1/128). Therefore the probability of this scenario is the multiplication of the two. The probability of getting the weird coin and getting all heads is (1/573). These now need to be normalized.

First outcome is (572 / 73344) and second is (1/573) or (128/73344). The ratio to them is 143:32 therefore the probability of the two events is (143/(143+32)) and (32/(143+32)).

So the probability of it being the two headed coin is 32 / 175.....I hope :P

EDIT: Ninja'd bad :P

EDIT2: @ieat...n = 1


Just kidding lol

When I saw you write n=1 my jaw literally dropped before I saw the JK

Re: MrRubix's Riddle/Problem Thread: Rebirth

We all know it is not n=1 but rather p=0.
You know I am joking.

Re: MrRubix's Riddle/Problem Thread: Rebirth

I think I have a solution to Emeralds Question....I almost forgot all about his question until just now
There is probably better solutions then mine though...
First off the order: RMS>AM>GM>HM

First Prove RMS > AM

sqrt((a²+b²)/2) > (a+b)/2
(a²+b²)/2 > (a²+b² + 2ab) / 4
2a²+2b² > a²+b² + 2ab
a²-2ab+b²>0
(a-b)²>0
Therefore RMS > AM

Now Prove AM > GM

(a+b)/2 > sqr(ab)
(a²+b² + 2ab) / 4 > ab
(a²+b² + 2ab) > 4ab
(a²+b² - 2ab) > 0
(a-b)²>0
Therefore AM > GM

Now Prove GM > HM
sqr(ab) > 2ab/(a+b)
ab > 4a²b²/(a+b)²
ab(a+b)² > 4a²b²
(a²+b² + 2ab) > 4ab
a²+b² - 2ab> 0
(a-b)²>0
Therefore GM > HM

I hope all that is right...I haven't worked with equalities in a long time and forget if there are some rules that flip the inequality sign. :S Oh well. Either way though I am pretty sure on the order, even if the proofs are off.

EDIT: @Rubix, I had a feeling that I was gonna piss someone off for a second lol. I was going to white out the JK part but thought better of it :P

Re: MrRubix's Riddle/Problem Thread: Rebirth

Here's a cool riddle I came up with...

Bethany, George, Irvin, Oliver, Ronald, Vance, Walter, and Yolanda all pile into the FFRMobile, but they soon realize that they're one seat short. They decide to kick someone out. Who gets the shaft, and what is his/her favorite number and color?

[DayMan951]

Re: MrRubix's Riddle/Problem Thread: Rebirth

I guess Walter gets kicked out, and his favorite color is white. I don't know his favorite number so I'll just say 8.

[MrRubix]

Re: MrRubix's Riddle/Problem Thread: Rebirth

Ieat: You sure you aren't forgetting Paula?

Assuming I am understanding this correctly...

Bethany (blue, 8), George (green, 64), Irvin (indigo, 48), Oliver (orange, 32), Ronald (red, 4), Vance (violet, 12), Walter (white, 192), Yolanda (yellow, 16)

[pntballa18]

Re: MrRubix's Riddle/Problem Thread: Rebirth

i'm gonna go ahead and say walter, white, and 192

because ROYGBIV doesn't have a W in it, and based on rubix's post i'm guessing 192 is the wavelength or some **** of white

[MrRubix]

Re: MrRubix's Riddle/Problem Thread: Rebirth

I'd say Walter purely because of ROYGBIV (also explains why there's no Paula ), and 192 because I am equating numbers to their note colors/types in FFR (hence the FFRMobile reference). White notes in FFR are 192nds.

Re: MrRubix's Riddle/Problem Thread: Rebirth

Hehe, Rubix beat you guys to it. Contextual relevance is sweet.

And yes, Paula (or whatever similar name you prefer) was left out because her favorite color is not a fundamental component of the visible spectrum.
