Default Re: GMAT question - symantic problem?

[ QUOTE ]
The sentence "How many different possible entries exist in which all three digits are not equal?" is ambiguous between (1) How many different possible entries exist in which it is not the case that all three digits are the same digit?; and (2) How many different possible entries exist in which it is not the case that any two digits are the same digit?

[/ QUOTE ]

I read the question as "How many different possible entries exist in which all three digits ARE equal?"
Then I took the the 'not' as meaning "all the other cases".
Obviously too simplistic, but I can't quite figure out why.
