Oh, Holly Shit

I just realised something.

Stupid me got 3.1414 for the probablilty, after getting the other maximum point(my calc did not show other max at 0.58).
  :x  :x  :x  :x  :x  :x  :x  :x  :x  :x  :x  :x  :x

And so I got the wrong value of Q

And so I got the wrong value of 'b'

DAMN!!
oping for an ENTER of 99+

now that i remember it i believe i got something close to p=0.5858 and q=0.5887, or some very very similar. i felt it was a little wierd that they were so similar but meh hahah. and b=20.9 does sound familiar too i think i had that.

Looking at the solutions, I don't think I did as bad as I first thought, still bad, but not as bad.

Can anyone remember how many marks the following questions were worth...these aren't the one's I got wrong, I can remember most of the other mark allocations, I've just totally forgotten how much the following were worth...

2g, 3a ,4d, 5fii

what value for b did u get? i hope we are talking abt the very last qn...i got b= 20.9


I used Probability =0.03044(from previous question) , and so got the wrong value of b(like 19.2 mins or something like that) . I hope I get consequential marks, because I did write down an integral.

From the solutions it seems I lost:
1 mark in Tassie Jones
2-4 marks in final part of prob question.
oping for an ENTER of 99+
