Make sure you do the lottery this weekend. I concede that the odds of winning that are significantly greater than getting 18/20 by guessing on this quiz but you never know.

it wasn't all guesswork! a few of them i knew either from prior knowledge or reading the book of general ignorance.

I did recognise a few of the questions. I generally worked on the premise of "least likely answer is correct".

actually, i reckon you have a significantly better chance of winning the lottery than you do of guessing at least 18 out of 20 on that quiz. james m just being modest.

18C20x1/4^18x3/4^2 + 19C20x1/4^19x3/4 + 1/4^20 &lt;&lt;&lt;&lt;&lt;&lt;&lt;1/14000000 I think.

nah, you're underestimating how tiny 0.25^18 is really going to be.

i just worked it out and it comes out to about 1 in 620 million.

ha, just realised that's what you said. i need sleep.

Worst so far..

actually no, I got the &gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt; sign the wrong way around, forgot it was 1 over the number.

It's not 18^1/4 btw, see what I put as the actual sum, I can't be bothered working it out though. Will be greater than 1 in 14m though.

Grrr. Work

When's the repeat?

And who wants to work out the odds that I'll be in work for that too?
