  1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  2. Wait patiently for a helper to come along.
  3. Once someone helps you, say thank you and close the thread with:
    +close
  4. Feel free to nominate the person for helper of the week in #helper-nominations
  5. Do not ping the mods, unless someone is breaking the rules.
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

ignore what I've written underneath the question but im a bit confused with the wording of this question

#

is 55% for the intersection

#

is my tree diagram wrong

#

and if its conditional how do u represent it on the diagram

supple quail
#

Yeah, it is confusing. As written, it says that only 80% of the jumbo eggs come from Farms A and B? But those are the only two farms the store buys eggs from, so that's impossible.

wary moss
#

😭

#

so the question is wrong

#

this is the answer

#

im just confused where to put the values on the diagram cause isnt the intersection written at the side

#

so in that case why r they timsing

supple quail
#

This tells me that what the question is supposed to say is that 55% of the eggs from Farm A are jumbo, and 25% of the eggs from Farm B are jumbo.

wary moss
#

it does say that

supple quail
#

That's a different statement.

wary moss
#

phhhh

#

yeah

#

ok so

#

that would make the 0.55

#

go on the branch

wary moss
supple quail
#

It's P(jumbo|A) vs. P(A|jumbo).

wary moss
#

where would u put that on the diagram

#

does it fit

supple quail
#

Okay, you need to maybe stop trying to fit everything into the diagram and just start thinking about it in terms of Bayes's theorem.

wary moss
#

this?

supple quail
#

Yes.

wary moss
#

tbh I've never seen that before but it doesnt look that hard to understand

#

what about this is relevent

supple quail
#

...because you want to find P(B|not jumbo).

wary moss
#

this is the one my teacher taught

#

oh

#

yea

#

I think I got the rest of the question

#

I think it was just bad wording
