ok bump. I know how to do a but B is very confusing. mY teacher put worked solutions up but I don't get when u draw the 2nd tree for when they pick the second person, (if first person is married woman). Like how does it affect that treeView attachment 49521

wait what the hay bahaha are we in the same class?? lol
anyways, if you know the first person picked is a woman, then that means that there's one less person you can choose (bc u cant choose that woman again) meaning that the total amount of people goes from 66 to 65.
the number of males stays the same, so the number of married/unmarried men is unaffected and therefore the chance of a man being unmarried is 21/65.

to go a little further, since a married woman has been chosen, you can also consider how that would affect the sample space of women. it will reduce the total amount of people to choose from by 1, but also reduce the number of women in specific by 1, making the chance of choosing a woman 31/65 (which adds up)
this also means that the number of unmarried women is unaffected, and will be 13/31 whilst married women is affected and will be 18/31

if u wanna practice these kinds of calculations, these are multi-stage probability questions where the events are dependent on each other, like choosing something without replacement

year 12 too long too stressfull too much hell nah

 

[dillydally]

fried yes in terms of stress and just time waste bruh

ngl im only looking foward to getting a more manageable or smaller class. my grade is known for being rude asf to teachers so theres always someone crashing out in class and stressing me TF out.... if not then double kill ig

 

[bigupsanky]

year 12 isnt worth it like imagine yourself getting a 99.95 atar but you realise that u couldve spent time watching the new avengers movies coming up, spiderman beyond the spider verse, jjk season 3, one piece episodes. You're missing out on everything bruh

 

[Reasonabledoubt]

people base their whole identity on their atar like it pmo sometimes icl atar this that just relax

 

[dillydally]

i cant imagine studying for a perfect atar and all the cortisol spikes being worth the while

 

[GBH]

ok
