if not a and b are disjoint, does it follow that B must be a true subset of A
does the intersection then become:
just P(B) or P(B)/P(A)? is the intersection suppose to tell us how large part of their shared part makes up of the whole, or, how large part the smaller makes up of the larger event

do...
If by "true subset" you mean a proper/strict subset, then not necessarily. It's possible B = A.

no i mean by true that they could equal
solemn hill
Then... you just mean "a subset".
prisma dust
Then... you just mean "a subset".
oh yes
true subset is when its cant equal
but i guess, the terminilogy aside, my thought is right?
just P(B) or P(B)/P(A)? is the intersection suppose to tell us how large part of their shared part makes up of the whole, or, how large part the smaller makes up of the larger event?
I think P(B) just

I don't know what "P(B)" means.

probability of even B

...okay, you're mixing probability theory and set theory in confusing ways.
prisma dust
well they relate right, a set in this case is an event
a probability of that event is the cicle in the venn diagram
solemn hill
Probability can't be a circle. Probability is a number.
prisma dust
Probability can't be a circle. Probability is a *number.*
yeah but its represented by it
you just need to adjust the size according to the number
where the whole space equals 1
solemn hill
...you can do probability theory on sets.

That's like saying a flag and a slice of bread are the same thing because they're both rectangles.

Say, P(A) = 0.4, as in picture above
