Probability is not my strong suit but this is what i think.

P= number of ways 4 can be chosen from 14 / number of ways 4 can be chosen from 17

P= 14C4 / 17C4

P = 1001 / 2380

$$\mbox{P(all 3 survive) }=\frac{1001}{2380}=\frac{143}{340}$$

$${\frac{{\mathtt{1\,001}}}{{\mathtt{2\,380}}}} = {\frac{{\mathtt{143}}}{{\mathtt{340}}}} = {\mathtt{0.420\: \!588\: \!235\: \!294\: \!117\: \!6}}$$

Can another mathematician please check this - I'm fairly confident that it is correct.

What are you talking about?

That zero is a infinite weight upon your shoulders.  This is indeed true.

Hence let it be proclaimed that  $$0=\infty$$  is now indeed proven!

This shall be legislated in the land of Camelot!

This decree is the most important of all time and will remain so until  Indianna's legislation for $$\pi$$  1897!

By the order of Lady Guinevere

(Supreme Ruler of Camelot in the absence of King Arthur)

You are the only one who is likely to be telling zegroes this!!

But then again since you are "someone who knows everything" 

It follows that you must be right.  

But - assuming that you do indeed know everything - you may still tell lies - and if you tell lies then maybe you really do not know everything - It does sound like a circular arguement - We need Sir Cumference here to arbitrate!  

I wonder if he is handy?

Perhaps Sir CPhill could take his place if Sir Cumference is not about the royal cylic quad?

Do you mean

LCD of  $$\frac{-2}{x^2-2}\mbox{ and }\frac{2}{x-4}$$  ?

then the answer is

$$(x^2-2)(x-4)$$

You will need to give us more information.  I don't know what you are talking about.

What are you talking about?

Anonymous doesn't get any credit for the points - although he/she can see them.

I think the verbal praise is more important to everyone but especially to the anonymous people.

You did good anonymous. Thank you 

Volume of pyramid = 1/3 * area of base * perpendicular height

At the moment there is an invisable decimal point after the 5. (in 25)

The negative indice indicates that it is a very little number.

You have to move the decimal point 5 places in the direction that makes the number smaller.

Do it yourself and post the answer.  We will look at it and tell you if you get it right or help more if you don't.
