re-obfuscated
consider the following:
I. exactly two of these statements are true.
II. two of these statements are false.
III. only one of these statements is true.
i used to think that there were the following possibilties:
none of them are true, or
I. is true, or
II. is true, or
III. is true, or
I. & II. are true, or
I. & III. are true, or
II & III. are true, or
all of them are true.
--
if none of them are true, then II. must be true.
if only I. is true, then I. is false.
if only II. is true, then III. is true and II. must be false.
if only III. is true, then II. is true and III. is false.
I. and II. can't both be true, they contradict each other.
if I. and III. are true, then III. is false,
if II and III. are true, then III. is false.
if all of them are true, then all of them are false.
are you still reading? seriously?
