A Cuckoo-Instructor who is severely brain damaged is not only stupid and insane but also unable to realize that he is so. As a result he speaks truth 3 out of 4 times. He throws a die and reports that it is a six. Find the probability that it is actually a six.

a) 3/8

b) 5/8

c) 7/8

d) 1/12

e) 9/10

PS: In fact the Cuckoo-Instructor is so insane that in a fit of insanity he started to claim himself to be extremely agile which was in fact his major brain screw up and could not realize that he is actually hallucinating and not telling the truth.
