A Logical Draw
Three puzzle competitors are
blindfolded. A white piece of paper is glued to each one’s forehead and they
are told that not all the pieces of paper are black. The blindfolds are removed
and the prize goes to the first man to deduce whether the paper on his forehead
is white or black.
All three announce white at
the same time. Why?
