What is a convex quadrilateral

alpine ledge
#

bruh

#

you cant find an answer if you dont know what a convex quad even is

echo barn
#

I just checked, so hmm

alpine ledge
#

so?

echo barn
#

Probability density function, put it as a constant if (x,y) in the circle, 0 if it's not,

#

Sec I'll try in a paper

#

Can I see what your solution

alpine ledge
#

yeah hold up

#

i got (12 pie ^2 -35)/12pie ^2

echo barn
#

Alright, Ill try to figure it out

alpine ledge
#

alright

echo barn
#

Try draw ABCD quadrilateral inside a circle, now you will notice that only 1 of 3 of the total cases is a convex quadrilateral, so I think the answer is

#

Maybe not sure

#

Actually wait

#

1/3

#

Pi/3 / Pi = 1/3

#

Could be wrong

#

Do you have the answer

Great

alpine ledge
#

rigorous solution tho2-3 pages

#

do u want to see the solution?

echo barn
#

Yes of course

#

That's huge, it's good tho, I just read the idea, did you find a faster route ?

#

I think calculating the probability of a point inside all possible triangles inside the circle is the way to go

#

Like they did, multiply it by four times for 4 points of course 1 - all of this

#

Finding a formula for iterating through all triangles is the hard part, but it's doable, thanks for the solution

alpine ledge
#

there is another way

#

but you need to know sylvester four point problem

echo barn
#

I'll save this, to look at it later, thanks for the opportunity
