Posted: 28 Oct 2011 01:25 AM PDT

The solution depends on how you consider the answers... you can say that
there are four unique answers (A, B, C, D) or you could say there are only 3
answers (25%, 50%, 60%). It's a trick question! Hahahah
Oops fat fingered earlier email. I think this, as Tyler sez, is tricky
because of the double 25. You have a 50% chance of 25, but only 25% of the
other two. Like the Monty Hall, I'd like to hear a pro reason through to
the answer.

Imagine it's not multiple choice...

Zero. Because the actual correct answer is herring

Self-referential statements can lead to paradoxes, so one could say the
question is not well-formed because it is self-referential.
If, as mentioned, choice (C) were 0%, and options (A),(B),(D) were unchanged,
then the question leads to a paradox.
If choice (D) were 50%, and options (A),

For Russ Standish, the question is

And here's my plodding answer.
If 25% were the correct answer, then either (a) or (d) would be right. So
one would have a 50% chance of getting the correct answer. Hence 25% is not
the correct
Here's how I'd analyze/state it.
It all revolves around the first 'if' statement. If I choose an answer
at random then I can't let any information from that answer influence my
result or it wont be random. Since there are 4 choices and now I can't
pay attention to what they are, then at
If we take this seriously, which I doubt we should :), I think you'd have
to create a tree of probabilities much like monty hall problem. (at least
if there isn't a trivial nifty solution!)
So start at the root of the tree, generate a branch for choosing each of
the three answers, 33.3% each.
OK .. I'm likely to buy an Android phone, but I confess I'm confused by the
differences between the handset manufacturers.
They all attempt to have somehow improved on the core Google software.
And some/most of the phones are locked and/or require jailbreaking to do
do fairly standard things.
