Prove that I is transitive: xIy and yIz --> xIz for x, y, z in the set of alternatives.
Homework Answers
x|y means x preferred over y
y|z means y preferred over z
results to, x|z means x preferred over z
And the transitive implies the exactly given situation if z|x i.e., z preferred over x than it would not be the case of transitive
