Yep that, could also replace the -\infty with 0.

Guys he said more than twice.

Re: HSC 2015 4U Marathon - Advanced Level It's just saying that when the n'th passenger enters, the only possible seats left will be his own or the first person's. Both cases are equally likely so it's just 1/2.

This can be found using complex analysis in a VERY cool way.

Re: HSC 2015 4U Marathon n has to be odd, and since 2 and 3 are co-prime three consecutive odd numbers must take all possible values mod 3. This means there is exactly one of the values equal to 0 mod 3 and hence composite.

Which graduates besides myself are coming? And which could even get over 70 lol.

At least 2* but see below True but they take into account other maths courses. Say A and B both get 97 raw in 4U and are ranked 1st internally. If A gets 70 raw in 3U but B gets like 68 raw, then A ranks above B in the 4U list.

In 2013 four of the state rankers (including 1st) did it and didn't get 70. Also last year an Olympiad did it and didn't get 70.

Your method doesn't prove for any values of t. You would get 0 no questions asked.

The trend is usually 65/100 raw gives you a band 6. Depends on the exam each year though.

Just work hard and do your best in the final exam. Since you are 1st, you can still get a really good mark.

Engineering scales pretty shit tbh.

tbh I suggest giving MC a legit attempt. It's the easiest 10 marks of the paper.

Good luck getting over 70 when the exam is out of 70.

I feel like I know what it is now. Though it probably isn't what I'm thinking since you wouldn't be that obvious.

Yep, get over 70 in ext 1 and i'll shout lunch. I'm confident no one will.

I'll make the bet for Ext 1 too.

Sure, I made the bet last year and no one got over 70 so why not.

Will be coming to this again for the fourth year straight :) Pretty much acting as a control now to see difficulty over the years.

LOL why are you asking Optiver about actuary salaries? They dont do that brah
