Imagine a simple chocolate bar promotion in which there is a 6 in 1 chance of winning another bar. My question is; If you buy six bars, what is the chances that at least one will be a winner?

They don't have to hit the same point on the target - they just have to hit it at the exact same time.

So does that mean that the probability of two arrows hitting a target at once is the same as with three?

A quote from Rutherford: "All science is either physics or stamp collecting." Thus I like to think of physics as the only science; hence what makes it so special (to me at least). The irony is that Rutherford actually managed to get a Nobel Prize in Chemistry, which perhaps goes to show that...

I'm not sure what the atmosphere on the planet would be like, but I'm sure that the local residents would be unnecessarily hairy and their dialect would tend to be filled with entertainingly nonsensical rhyming words. Oh yeah, and they like to eat green eggs and ham.

Yes - I would also like to have that formula. Does nobody have a brick? I am yet to learn calculus so I suppose I shall have to ask a maths teacher how to do this next week...

But surely it is possible for two arrows to hit a target at once?

Can somebody provide an example with what we have established so far? Just use a brick so I can see how it is done. Thanks.

As there are an infinite number of time frames, does that mean that the probability of two things happening at the exact same time is one in infinity? (For example, two arrows hitting a target simultaneously). If so, what is the probability of three things happening at the same time? Less...

Thanks guys So the formulas are: \iiint\frac{-G\rho}{\sqrt{x^2+y^2+z^2}}\, dx\, dy\, dz and t=\frac{1}{\sqrt{1+\frac{\phi}{c^2}}} What is "d" in the first formula?

Could you please post the code? I can always use a LaTeX sandbox to view it properly. \phi=\iiint\frac{-G\rho}{\sqrt{x^2+y^2+z^2}} <== is this it? And what is the full time dilation formula?

That would probably work but it seems very tedious - I would have to keep drawing spheres until I decide that they are small enough, and then calculate each individual sphere's mass and then their time dilation and then multiply it all together. Is there an easier way?

I'm sorry but I still do not understand. Please forgive my limited physics knowledge but I would still like an example.

There seems to be some discrepancy in regard to how this is calculated; could somebody please provide an example for me?

What I am looking for is the gravitational time dilation on the surface of a stationary body. Assume the body has uniform density. What other information is required?
