Max, do you have access to Wolfram|Alpha,

the pay version?

I did it there.

I've downloaded the answer to my computer but Tiny Pics refuses to upload it - probably becasue it is very long .

So I can't post it easily.  

Do you want me to continue to try and post it here or have you got the problem sorted now.

(I have not personally worked through any of the mathematics for it.)

It is an equation :/

John rolls a pair of standard 6-sided dice. What is the probability that the two numbers he rolls are relatively prime? Express your answer as a common fraction.

Great work Ninja :)

sorry EP our guest is right :(

Thanks for the explanation guest. :)

\(P(relatively \;prime)=\frac{23}{36}\)

There are seven wombats in a council. Three of them are hairy-nosed wombats, while the rest are all different species. If the hairy-nosed wombats are indistinguishable but the other wombats are, how many ways can the wombats seat themselves in a row?

The real meaning of this question is difficult to determine....

I think that both answers have merit.

there are 840 different ways that the wombats can sit, just like NinjaAnswer said,

but if you only care about the position of the 3 hairy nose wombats then I think out guest is correct.  :)

Yes that is a good alternative to mine and Alan's approach.  

I think Alan did it my way, or  I should say I think i did it his way  ://     

I had forgotten aoubt LancelotLink's campaign for office.  

Thanks Ginger, the memory has bought a big smile to my face :)

I wonder if LL is still off, licking his wounds, from his great defeat??

Well it would be excellent if Morgan Tud would appear and recomend a fix. That be the truth.

Euthanasia, yes tis possible, the good Doctor often be one to over prescribe, a good sleeping draft be all that is needed. ://

This realm would hardly be recognisable to Churgeon Tud on this 1st day of January in the Lords year two thousand and seventeen.  Tis sad but although one can deny the existance of evolution one cannot stop its advance.  

I think that the bridge for which the troll extracted his toll has long since been swept away by the raging floods.  Perhaps the troll was also swept to his death.  Tis so sad. 

Ah ha I found the site I was looking for!!

Thanks Ginger,

Graphics are fun. :)

I was looking for an interactive graphic that I have seen and probably used before in mathsisfun.  I found some related  interactive graphics,  but not the one I was looking for.  It is a little frustrating when this happens.

I probably should look in my old information threads, I may have stored the address there, ...

mine I guess LOL   :)
