Hi, yeah I didn't know how to write those signs on the forums..
So, could this expression (Not A and (Not A or/and Not B)) then be simplified to (Not A and Not A) and ( Not A and Not B)? This part is what I don't understand..
Homework Statement
P(A) = 0.3
P(B) = 0.5
P (A and B) = 0.2
Find P (Not A, given not A or/and not B)?
The Attempt at a Solution
So I think
P (Not A, given not A or/and not B)=
P (Not A and (Not A or/and Not B)) / P (Not A or/and Not B)
Is this correct? But I don't understand...
Hi,
Actually, although it says Vq, I think it means V(q). This would mean: given the price, p, the expected value of the object, which depends on its quality, is greater or equal to p? Sounds a bit strange, though, I think?
Homework Statement
E(Vq | p) ≥ p
p = price q = quality V = value
The Attempt at a Solution
Well, it's something to do with expected value to be greater or equal to price, but that's as far as I get really. Don't get what this means (Vq | p). Any help is appreciated!
