Ah, yes. I think perhaps I 'over-complicated' things. Thank you VERY much for your assistance, sir. I am indebted.

Please forgive me for not clarifying earlier, I'm trying to answer (b). I know that .5 is the answer for (a), but I'm getting .5 and .3 for answers for (b). I got .5 by going this route: P(AUB) = .9, P(AB) = .5; the compliment of A is .4, if the compliment of A occurs, that leaves .6...

I mean when looking at the diagram: if the compliment of A occurs, that means that A will not occur, and P(AB) will also not occur; that just leaves .3 left inside of B, and I'm getting .5 for the answer to the question, not .3

P(AUB) = .9, P(AB) = .5; the compliment of A is .4, if the compliment of A occurs, that leaves .6 insides the sample space, right? With .1 of that being the intersection of compliment of A and compliment of B, so that leaves .5 left, but that doesn't make sense looking at the venn diagram. Am I...

So I have drawn the venn diagram and I understand what you are saying about the areas, but I still don't quite understand what area constitutes my answer. I want to assume that the two, A and B, are statistically independent, which would give .8, but i know that's too easy. A little more help...
