Expected Failure

Mood: Static & Lost
Song: Dance with my father by Luther Vandross

An Exam consists of section A, B and C. Each section is worth 20, 50 and 30 marks respectively. Let Y be the event that a student fail in the test where passing marks is 50%. Let X be the event that the student fail miserably where he score less than 20%. In both events the case is independent.

a) Find the weightage where a student did half of section B, do anyhow in section A and do only one question out of 2 in section C?
b) State the probability the student fail in the above event.
c) If the student fail miserably, find the probability that he fail in section B, P(B/X)?

That is the sample of a dumbass module that i took and i am gonna fail miserably. I sense that. A huge sign of discomfort was in the air when the lecturer announced we have 15 mins to the exam. I can feel the tense in the room. As soon the lecturer announced that, my MCQ were totally blank. 10 MCQs questions. How do i not panic? And when the time lecturer signal the end of paper, everyone in the room feels as though we've been slapped by the lecturer. Total stunned. With mouth open staring what the outcome might have been. A total diasappointment. I am mentally drained by the last paper. Statistics make me cry. Probability of failing? Definite!!! Lets just wait. I seriously dont feel good. Really.
