probability question

[hushed lantern]

@tidal quartz there, send the question again here

[hushed lantern]

Which subquestion were you asking about ?

[tidal quartz]

question 2c, the attending university

sorry for in-clear info..

[hushed lantern]

And draw the path you were talking about pls

[tidal quartz]

also the 2c

oh ya

[hushed lantern]

No, I mean on the probability tree

[hushed lantern]

The whole path, starting from the very left

[tidal quartz]

should i draw another more clear one?

[hushed lantern]

Because the circled U could both be used in the computation of P(U|F) and P(U)

[tidal quartz]

why can use in both? the proper path still in progress

P(U intersection F) = P(F) * 0.73
P(U) = P(U|F) * P(F) + P(U|F') * P(F')

[hushed lantern]

The yellow texts reads "both P(U) and P(U|F) use paths that go through that circled U"

I have to go now, I'll keep answering later

You can keep asking sending your questions meanwhile

[tidal quartz]

thank you so much for answering meeeee

[tidal quartz]

thank you, definitely will continue ask again XD

[tidal quartz]

how does you know this question required us read the number in that yellow way? because the question didn't special mention anything, so i calculate the P(U) in the way that you provided me in public channel...

or just because in the question ,the front of "attended university" have a "female" event, so have to read in yellow way?

[hushed lantern]

The yellow is just to emphasize on the presence of the U in the green paths

[hushed lantern]

I don't know what mutually exclusive means (haven't studied probability in a while), I just sent the difference between P(U) and P(U|F)

It's up to you to decide how you should use these to fit the question's requirements

[tidal quartz]

alright, thank you so much how you put so much effort to answer my question😆

nice to meet you Quentin😄

[hushed lantern]

No problem !
