comment Creating Venn Diagram To Aid In Solving Probability Question.
Okay, I was able to solve part (a), but (b) is giving me a little trouble. From what I read, the cardinality of the event (set) that contains the outcomes (elements) where only inspector B finds a joint defective should be $|B \cup A'| = 751$, the probability being $P(|B \cup A'|) = 751/10,000 = .0751$. The true answer is, .0435. What did I do wrong?

All right, I've figured out part (a). For part (b), are those two sets complements of each other? Finding the probability of the union of the two sets wouldn't be all that help; it would only tell me the probably that all five get electric or all five get gas. How would I solve part (b)?

Oh, you're are right. So I just left out a one event (element) in the set--namely, $ggggg$.

comment Probability of Purchasing
let the event $A$ be such that it will contain the outcomes where only one person buys an electric dryer. Then $A = \{egggg, geggg, ggegg, gggeg, gggge\}$, right? So, $P(A)=.428$, right? I ask these questions, because putting things in terms of symbols helps me more often than not.

comment Probability of Purchasing
Do you happen to mean that, "at most two," is the complement of "at most one?" Because it doesn't take about "at least one" in part a). If is true, then you are saying that, out of everything that can happen (the sample space, which has a probability of 1), is composed only of the even that at most one person buys an electric dryer and at most two people buy an electric dryer? What about at most three people buy an electric dryer?

Oh, yes, I see clearly, now. Thank you!

Well, how do we account for the fact, in your explanation, that $A_3$ contains portions of $A_1$ and $A_2$?
