Prob test = count the no of ways to fail

The probability test consists 4 qns, all with difficulty level 3000 that kind.
P(event- fail the test) =
P(anyhow whack qn1)+
P(look at Qn2 for half an hour and still dunno wat is going on) +
P(stare hard at Qn3 then try to tell yourself that you know how to do, when in actual fact, never see before one) +
P(start your calculations then realise that u do wrongly, then u cancel everything and do again, but this time u careless, and count one less sample)

so the required probabilty is 1, n i really have a bad feeling...
