Hey guys...maths is my worst subject as well, always hated it...my little bro who's in year ten has been helping me with some of the stuff this year....thats saying something right?!....i really like the idea of this study group......

 

[Happeninchick]

Hey guys! Maybe someone could start the ball rolling and fire away with a question or a problem in General Maths. I'm a 2004 General Maths student, so I'll try to help out as much as possible, when I'm online!

happening chick...what mark did u end up getting for maths.....
my question is.....theres five men and three women on a island..if one person is selected at random to leave, what ia the probability that this person is female

 

[want2beSMART]

there is 8 people total on that island where 5 are male and 3 are female so therefore the probability that the person having to leave is female is 3/8 chance

 

[NoToRiOuS87]

thanks...yer i just realised how easy that was...i thought it would be more complecated

 

[craz]

When you say more complicated did you mean like the probability where you must multiply or like tree diagram situations. ???

 

[Happeninchick]

Hey Notorious. I got a Band 6 in General Maths with 94.

 

[SophieB2]

OK, well...
Q:
Mean is 6.25%
Standard Deviation is 0.25 % Harlan gets a reading of 5.75% What is Harlan's reading as a z- score?

I learnt that today. Harlan's z-score would be -2

Ha, how easy is general! i love it! i dont have to do anything and i pass all my exams with flying colours
How is everyone else finding general?

theres five men and three women on a island..if one person is selected at random to leave, what ia the probability that this person is female

It would obviously be 0% chance, as they'd whinge and cry about having to leave and eventually after no resolve one of the males would just go 'fck this, I'll leave the island... ffs..'

 

[sally_33]

if it asks us to copy and complete a table, draw a diagram or draw a graph are we supposed to use pencil??

 

[danster]

From my understanding the papers get crushed together causing pencil drawings and what not to be blurred. I do recomend however using a pencil to draw it at first (you may make a mistake!), then if you have time at the end; go over it with a pen.
