i think u can... i mean if u only lose 7 in P1 then u can easily get an A.... or even if u lose like around 10 i think... it depends on the gt
and A in p1 and a B/even a bordeline C in M1 can prob score a borderline A... *optimism* ^__^ Good Luck... and pray for us all

Q5 (ii)someone explain ! please

See they have asked for the expected profit and in stats when the word expected comes its obvious to use the formula for E(X)
known as mean. So first find the profits possible and there r only two ways, first there is a revenue or no revenue at all. So we know the prob. of getting more than one fail wich is 0.264. Now find prob. Of less than or equal to 1 fail 1-0.264
With revenue profit is (450x10)-(24x20)= 4020
No revenue 0-(24x20)= -480
Now multiply the profits with their respective probabilities 4020x(1-0.264) and -480x0.264
Add both u get the answer.
