ok let's play probability game
in a test, the passing mark is 50.
there are 50 true or false answer. each correct Q will add 1 mark but each wrong ans will deduct 0.5 mark
then there are 10 essay Qs that have 5 mark each......
assuming that the student only scores 20 to 30 marks for his essay Q, what is the probability of the student to pass?
