Do you know the right answer?

anonymous · Answer

Well I know that the possible outcomes for the test is 32

anonymous · Answer

And if I know that if at least one of the answers is correct it's 31/32

anonymous · Answer

"How many outcomes have more than one correct answer?" -- This is alluding  towards combinatorics not probability.

anonymous · Answer

Yes it is

anonymous · Answer

I thought it was 32-6 equal to or less than one correct answer but I could be wrong

@987poi: Do you know the answer for this question?

anonymous · Answer

No I don't

anonymous · Answer

I think it should be $ 2^5 -(5+1) = 16 $, but I will wait for  @Zarkon or someone else to corroborate.

anonymous · Answer

Typo: Read $ 2^5 -(5+1) = 16 $ as $ 2^5 -(5+1) = 26 $
