WebIf P (A)*P (B)=P (A)+P (B)-P (AUB) then the events are independent Let V be the event that a computer contains a virus, and let W be the event that a computer contains a worm. Suppose P (V) = 0.15 P (W) = 0.05 and P (VUW) = 0.17 Find the probability that the computer contains both a virus and a worm Find the probability of V intersection W Webanswer: P (A' n B' = 0.45 [finding the probability of just A] P (A n B' = P (B) - P (A n B) = 0.4 - 0.15 = 0.25 [finding [the probability of just B] P (B n A' = P (B) - P (A n B) = 0.3 - 0.15 = 0.15 therefore [probability of A or B] P (A u B) = P (A n B' + P (A n B) + P (B n A' = 0.25 + 0.15 + 0.15 = 0.55
WebP (A, B) vs P (AuB) vs P (AnB) What's the difference between these three? My understanding is that (assuming independence?) P (AuB) = P (A) + P (B) and P (AnB) = … WebP(A∩B) is the probability of both independent events “A” and "B" happening together. The symbol "∩" means intersection. This formula is used to quickly predict the result. When …
WebP ( A ∪ B) = P ( A) + P ( B) − P ( A B) = P ( A) + P ( B) − P ( A) P ( B) = 0.2 + 0.8 − 0.16 = 0.84 Your working seems fine but be careful of careless mistakes. Note that independence is used so that we can compute the intersection probability P ( A B) = P ( A) P ( B). Share Cite Follow answered Sep 14, 2024 at 18:57 Siong Thye Goh 146k 20 86 149
WebSolution The correct option is A 7 12 Explantion for the correct option: Finding the value of P (A): P (AUB) + P (A∩B) = 7 8 and P (A) = 2P (B) .... 1 We know that, P (AUB) = P (A) + P (B) - P (A∩B) ⇒ P (AUB) + P (A∩B) = P (A) + P (B) = P (A) + P ( A) 2 ( from 1) ⇒ 7 8 = 3 P ( A) 2 ∴ P (A) = 7 12 Hence, option " A" is correct.
