bionomial probability 5c3x3/4^3x1/4^2 + 5c4x3/4^4x1/4 + 3/4^5

Well he stopped talking 3 days after you joined and he is from hong kong :P

but the question says when the prize is finally won.. they only answered it for when the prize hasnt been won after the 25th time. Nothing to say that the prize will be won.

Hey, I just dont think they are right with their answer. 1995 Q5biii ..... In a jackpot lottery, 1500 numbers are drawn from a barrel containing 100,000 tick numbers available. After all the 1500 prize-winning numbers are drawn, they are returned to the barrel and a jackpot number is...

thats why you would never be asked this question... you might be asked one that the sum of coefficients are zero

8^17 - 17c1x8^16x5 + 17c2x8^15x5^2 - ... .... - 5^17 i dont really see any easier way of doing this? :s what a silly question.

hes got a challenge with final fantacy.

yea its 30... but... committee is a 3unit section.

he was just having a look at the solutions, and didnt understand how they skipped to that line.

hey, if u dont understand, you dont even need it for this question the first person can have any birthday so his probability is 1, now, second person has 1/365 chance of having the same birthday as the first person. Leap year is ignored. Anyways: if this was say, more than 2 people...

1 - 365p2/365^2 = 2.739726027 x 10^-3 = 1/365 if theres 23 people theres 50% chance and 45 people.... 90% :P

yea cause people from James Ruse dont really bother with EE2. (im sure alot of them do ee2, but not the super kids - they would more be concered with maths) they dont do the subject, their more concerned with easiest way to maximize uai. To do that... english advanced, all 3 sciences...

your stuck between those 2 lines? :| look it says 4(<b>5</b>m) + <b>5</b>(9^(k+2) common factor of 5... dont be scared if the 5 is in the bracket....

can we use z=ei@ in the hsc?

get 1 mark for Q2 b haha

no C or P in 2unit...

yea that question is like from the 70's. I have a sheet too from the 70's of locus that uses those 2 words. That my teacher gave to me cause she said are the best. You wont get it in the hsc these days. well they would do this "meets the Abscissa (x-axis) and the ordinate (y-axis)"...

depends how confident you are, because you can easily get "better" with your answers of easy questions than hard ones. This would be the best way to boost up your marks. Especially some silly SHM question with like a very easy word answer question that you might not really like, or super gay...

its just for awards night n dux etc.. but its stupid because every subject decides to scale marks and before you know it everyone is getting 99 in everything. they should only scale extension subjects, english n sciences.

Which question did u get a mark off do u think? It would be in Question 8 since there is no exemplers for Q8. Q8aii?
