Multiple choice is just legendary. Makes life a'lot easier, no need to think or study and still got a chance to get full marks.

Example:
If there are 12 multiple choice questions, what is the probability if when you guess to get all answers correct?

P(All) = (1/4)¹⁰
= 1/1048576

See, out of all the outcomes "1048576" you still got "1" way to get it all correct.

Sorry forgot to add, 4 sig figs.....

but yeh not everyone can do that (assuming you legit did it in your head)
Why would I lie on a forum?

Anyway the 2013'ers who come to meats can vouch for it, they've seen me do this stuff irl.

Not saying your lying, but you can't expect me to believe you completely.

Judging by your other posts it seemed more true than a lie. Hence the 'assuming'

Realizenothing isn't lying. He is pretty boss at those questions.


Proves you can do everything in your head pretty much.

No it doesn't. Realise is clearly very good at maths, judging by this post and many others i have seen, but not everyone can and is supposed to be able to do them in their head. I mean it was a good estimate by him, but could he have done it to four significant figures in his head?

Can you estimate it to one decimal place?

Yes, my money's on that he can

But the point is, obviously not everyone can do this, nor are they expected to.

I could do 4 sig figs on paper in a min or so.

Possibly in my head if I tried hard enough.

I worked out your question in like 30 secs, if I tried for longer it would be more accurate.

She's my witness that I did this at meat:



I got it correct to 8 significant figures.

I did use paper but c'mon, even with paper that's freakin' hard.
