Mmm, multiplying across seemed to have happened when the "u" was backwards, so would i have to do the opposite ? Or mmm idk i get lost with these "u's"

OpenStudy (dm91):

best one to ask would be steve816

So basically what we have here are intersections and unions. The intersection (upside down U) a set that contains elements that are common to both sets. Then a union (U) is a set that contains all elements of those 2 sets. If two events (A & B) are independent, then P(A [upside U] B) = P(A) times P(B). P (A U B) = P(A) + P(B) - P(A [upside down U] B). Since they give you P(A), P(B), and what P(A U B) is. It's all in the matter of plugging it in the equation.

sooo.... it will be 2/3+4/5-8/15=P(AdownwarduB)

OpenStudy (anonymous):
