i need help figuring this out, i think choice E is also one of the correct choices. other than that I dont think there are anymore

ohh i cant choose more than 2 actually

#

hm

left pivot May 2, 2025, 1:08 PM

#

C isn’t correct

#

A is

#

Lemme check the others

#

@delicate sigil

delicate sigil May 2, 2025, 1:09 PM

#

thank you forletting me knoe

#

that leads me to believe E iscorrect

left pivot May 2, 2025, 1:12 PM

#

D is also correct

#

So a and d

#

@delicate sigil

delicate sigil May 2, 2025, 1:26 PM

#

i didnt eantlike a flatout ansqer of thequestion itself

#

Idk how to use latex 💀

#

left pivot Idk how to use latex 💀

can you explain it jsut through text?

left pivot May 2, 2025, 1:57 PM

#

Wait

delicate sigil May 2, 2025, 1:57 PM

#

when ppl use latex its usuallya little hard for me tounderstand anyway

left pivot May 2, 2025, 1:57 PM

#

$P(B\mid A)=P(A\cap B)/P(A)$

Lessgoooo

delicate sigil May 2, 2025, 1:57 PM

#

okay but

#

isnt that dependant

left pivot May 2, 2025, 1:57 PM

#

Wait wait

delicate sigil May 2, 2025, 1:58 PM

#

i understand that youre excited to uselatex

#

but im asking a yes or no question,politely

#

you can use it if youd like

#

but

turbid trench May 2, 2025, 1:59 PM

#

delicate sigil isnt that dependant

Yeah, you’re not given P(B) here to verify such. Unless P(A)+P(B)=1, even in that case I don’t think it works.

#

However, you’re given such for E and are this able to verify.

delicate sigil May 2, 2025, 2:00 PM

#

the reason i say E is bc in the multiplication aspect they dont have correlation i dont think

left pivot May 2, 2025, 2:00 PM

#

$P(B\mid A)=\frac{0.45}{0.5}=0.9.$

vale pondBOT May 2, 2025, 2:00 PM

left pivot May 2, 2025, 2:01 PM

#

Now, at P(B)=0.9

delicate sigil May 2, 2025, 2:01 PM

#

im looking for independent events

left pivot May 2, 2025, 2:01 PM

#

What is P(A) times P(B)

left pivot May 2, 2025, 2:01 PM

#

delicate sigil im looking for independent events

Ik, just a min

turbid trench May 2, 2025, 2:02 PM

#

The essential point here is that $\text{independent}\implies P(B\mid A)=P(B)$.

delicate sigil May 2, 2025, 2:02 PM

#

?

#

okay, i have been told that this one specifically is dependant in this chat i am pretty sure

#

so that just completely rules it out?

left pivot May 2, 2025, 2:03 PM

#

No, D is independent

delicate sigil when ppl use latex its usuallya little hard for me tounderstand anyway

please refer to this message

#

words are better for me to understand

turbid trench May 2, 2025, 2:04 PM

#

Okay, but the notation should be the same.

delicate sigil May 2, 2025, 2:04 PM

#

Kocher

#

Please listen to what im saying

turbid trench May 2, 2025, 2:05 PM

#

Independence implies that the probability of B given A is the same as the probability of B.

#

Are we given the probability of B here?

delicate sigil May 2, 2025, 2:05 PM

#

Thats not dependance?

turbid trench May 2, 2025, 2:06 PM

#

INDEPENDENCE.

delicate sigil May 2, 2025, 2:06 PM

#

that ehat i just asked

#

if youre going to use bold and caps like this

#

i dont eant help from you anymore

left pivot May 2, 2025, 2:06 PM

#

delicate sigil Thats *not* dependance?

If a and b are independent, the probability of b given a is equal to the probability of b

turbid trench May 2, 2025, 2:06 PM

#

I’m just trying to show the word that you should be using.

delicate sigil May 2, 2025, 2:07 PM

#

youre effectively makin gme feel stupid

#

thanks

#

i come here for help

#

and just because im not understanding as quick as you eant

#

its angering to you it seems.

turbid trench May 2, 2025, 2:07 PM

#

No.

#

There’s just specific vocab you should be using here to make a clear point.

delicate sigil May 2, 2025, 2:08 PM

#

so dont use caps or bold letters, please

turbid trench May 2, 2025, 2:08 PM

#

Okay.

delicate sigil May 2, 2025, 2:08 PM

#

just nevermind guys

#

thanks for helping as you could
