Hint Number Three

First, we'll alter the previous table just a bit (by changing the order of lines 2 and 3) so you can see more clearly what combinations of YES or NO answers you must base your decisions upon for the next two questions:

Six Possible Combinations
X
Y
Z
1
T
L

Since the Randomizer can answer any question with either Yes or No, you must consider the yellow "R" blocks as either "N/A" (not applicable); because you already know who the Randomizer is, or as being able to give you both a Yes and No answer to any of your questions. The solution, of course, is to be able to eliminate all the possible combinations except for the correct one. [I was just thinking about how such logic diagrams might relate to what programmers call either top-down or bottom-up programming!]

 

Still Lost? Or, didn't you even try!?   OK, click here for your yet another hint!
