I have been working on this problem (and looking through my book and the internet) and could use direction.
P(A or B)=.85 (A has line over it)
P(A and B)= .41 (A has line over it)
P(A or B)=.21 (A and B have line over it)
Find P(A/B) (B has a line over it)
I am not sure what the line means??
I could use some help---very appreciative!!
