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 how to calculate P (Not A and (Not A or/and Not B)). Could someone help with this part?
