why u got p3 and p3 twice and p2 and p2 twice :s-smilie:

As you can score that combination in two different ways. It's the same reason I have got P(3) x P(1) and P(1) x P(3).

that's not true yeah you can score P(3) and P(1) in two possible ways, but you can't score P(2) and P(2) in two different ways, that's nonsense whichever way u put it, it's allways going to be the same combination

For the Rohit question in S1 on 19/01/09 I got 0.18. I'd like to know what everyone else got?

lol yes indeed jdel

Why did people only take 4 as a possibility?

The answer clearly said at least 10 points, therefore he needed at least 4 points, he could have gotten 5 points or 6 points.
