But 450/1200 is probability
It's likely a 6 will be rolled 450/1200 times

I understand what you're saying, this is hard for me to explain lol.So anyway, I've gone and actually looked up the definition of probability. xD Anyway here it is (yes I'm obviously desperate haha)

1. The quality or condition of being probable; likelihood.
2. A probable situation, condition, or event: Her election is a clear probability.

450/1200 is not something which is probable, or likely to happen, that's just what happened on that occassion. Am I making sense at all? Am I being delusional? I'm convinced it's A lol.

The probability of an event is less than or equal to 1 (certain)

So 450/1200 is 0.375.

LOL maybe you're confused about the word probability? I agree that 450/1200 is not likely, but 450/1200 is simply the LIKELIHOOD of rolling a 6. The theoritical probability of rolling a 6 out of a non biased die is 200/1200 so therefore 450/1200 has a higher probability (chance) of happening. The probability is not HIGH but it's HIGHER.

I'm 99.99% sure it's C, as are most people. It can't possibly be A.

It's probably been explained before, but ill try and explain again LOL.

450/1200 = chance of rolling a 6.
750/1200 = chance of rolling 1, 2, 3, 4 or 5.

Chance of rolling either 1, 2, 3, 4 or 5 = 150/1200.

450/150 = 3

THREE TIMES HIGHER.

I hope it makes sense. If you're still conviced it's A then all we can do is wait 'til the answers are released? ...even though we won't care then coz we'll have our marks LOL

lol true. I guess I'm just convinced of my own reasoning lol, it won't surprise me if I'm wrong honestly. I will just agree to disagree now lol. I even sent an email to my teacher xD. I will reply if she answers it.
Edit: I understand how you get 3/8 from that reasoning fine, I just don't see 450/1200 being the likelihood. But anyway. I reread the question again, and I don't know. I convinced myself that 6 did occur twice as often as every other number, not just more so, so maybe it is C lol. But I'm not convinced. But anyway, I'm going to shut up about it now xD

 

[kirst21k]

sweet. i got all multiple choice right
but i screwed up the last question and the cheese one

 

[shell667]

Hey
It's 34% + 34% + 13.5% + 2.35% + 0.25%
= 84%

thanks, i made a stupid mistake thinking 65% of scores were between 1 and -1 instead of 68% haha

 

[laurenmhansen]

for that one i got 0.2 ml/min....im thinking im wrong cause every1 else is not getting my answers ...grrr!...i think its 0.2 because they have given you 1.6 standard drinks...and the MAXIMUM is one standard drink so hence you have to convert

lol, yeah thats what i put like 0.21mL/min. but guess thats wrong

 

[laurenmhansen]

I got 1/20 and 0.2mL/min too

haa me too, to both.
dam!

 

[croucher131]

yah same.

As for question 27 (a) part i wouldnt the flight take 9 hours. as 8334/913 = 9 ??

error carried forward, but if you did it correct in the first place. then you woudl get 9

 

[birdie-brain]

Oh, I think I've passed this exam... But I'm not confident :'(
I studied really hard for this too :'(

 

[wixxy2348]

yayyyyy I got at least 85 external so... with my internal rank/mark its looking better than i expected.
Yayyyy

 

[lochi90]

Theres a little formula i like to call present value formula!

agreed bro haha

 

[VeronikaB]

man, i can't rember my answers.
but que. 3
i think i wrote 24.
i am so pissed.

 

[jay9nine]

For question question 28, v, 2 a few people put puberty as the answer... it sort of is right though isn't it?

 

[wootywadwad]

I accidently divided by 1.852 to convert miles into km. Would this screw up marks for that whole section as the next questions are based on the first? Or would they give me CFPA marks?

 

[PC]

Very probably CFPA.

I'd say definitely, but who knows what they do at marking!

 

[kevinoconnor]

are these the acutal answers to the test
and how
u just work em out??

They were just worked out. They're not official answers. I'd say they're pretty accurate though.

 

[errriot]

(c) (i) 20.625 mL
(ii) 3.9 mL/min

Question (ii): It is recommended that blah blah blah a maximum of one standard drink every hour.
Express this as a rate in millilitres per minute, correct to one decimal place.

From (i): 1.6 standard drink = 20.625 mL of alcohol, according to your answers...

So how many minutes in an hour again?
According to your answers it's 3.3 minutes.
[20.625/1.6 = 12.89mL alcohol/std drink, 12.89/3.9 = 3.3 minutes]
Good work genius!

You're really going to go well in that exam... Can you actually tell the time?


The correct answer is 0.21mL/min, assuming that there are, in fact, 60 minutes in an hour.

 

[errriot]

lol, yeah thats what i put like 0.21mL/min. but guess thats wrong

no you're right... you're obviously one of the few even remotely intelligent people who do our level of maths...
