Official Exam 2 Discussion

[monicak]

If I use the 2006 data in Mao's SS calculator [since the 06 exams were considered easy], will that give me an accurate indication of what SS I should get this year?

[Tea.bag]

what ss would i get if i got 39/40 for exam 1 and 75/80 for exam 2???

low to mid 40s

I'm thoroughly disappointed that there were no normal distribution questions in either exam.

I'm disappointed there was only one question with related rates and no differentiation by recognition.

THAT WAS WAY HARDER THAN 06 OR 07

[davo]

agreed

way harder then 06 but only a little bit harder than last year

lol what'd you have to do for that question where you had to find the probability that the chick's first 4 shots were succesfull given that she got 6 out of 8 shots?

That muddled me up so bad

I don't remember this. I only remember that "what was the probability that exactly six shots out of eight were successful?"

i am so bad at maths =(
i get like D average for SACS and i think i got 55-60% for exam 1 and hopefully 50% for exam 2. is it still possible to get 30? or 35?

i try but i'm just bad at maths. i'm asian so i shud have the maths gene but i dont! haha

probably not 35, but 30 if you're lucky.

[melly04]

hmm 30 only if i'm lucky. yeah i hope i get at least 30. i hear it's easy xpesh cos dis yr's exams were considered tricky by most.
but i dunnoo...

What is the probability, correct to three decimal places, that her first 4 attempts at scoring a goal are successful, given that exactly 6 of her first 8 attempts at scoring a goal in a match are successful?

Combinatorics solution:

• Given exactly 6 successes == given exactly 2 failures
• Our probability space has these 2 failures anywhere in the 8 attempts, so 8 choices for the first fail * 7 choices for the second fail = 56
• The event we want has these 2 failures anywhere in the last 4 attempts, so 4 choices for the first fail * 3 choices for the second fail = 12
•

after checking the answers, i dropped 4 marks, oh shitshitshitshitshit!!!!!
If i get 38 for exam 1, is it possible for me to get a ss over 40 raw??
