P(A∪B) = P(A)P(B)−P(A∩B) Proof There is A∪(B∩Ac) = (A∪B)∩(A∪Ac) = A∪B, which is to say that A∪B can be expressed as the union of two disjoint sets Therefore, according to axiom 3, there is P(A∪B) = P(A)P(B ∩Ac) But B = B ∩ (A ∪ Ac) = (B ∩ A) ∪ (B ∩ Ac) is also the union of two disjoint sets, so there is alsoDon't forget to like, comment, and subscribe!!!Subscribe for new videos wwwyoutubecom/c/MrSalMathShare this video https//youtube/IoqYK6YlyBIThe problemRegister for FREE at http//deltastepcom or download our mobile app https//bitly/3akrBoz to get all learning resources as per ICSE, CBSE, IB, Cambridge & Www Ddtwo Org Cms Lib Sc Centricity Domain 1986 Distance learning notes on congruent triangles Pdf A^3+b^3+c^3-3abc proof
