Answer

AU(B∩C)={1,2,3,4,5}

Work Step by Step

U={1,2,3,4,5,6,7,8} A={1,2,3,4} B={1,2,4,5} C={1,5} We need to find AU(B∩C). (B∩C) represents the elements common to both the sets B and C. The common elements are 1,5. (B∩C)={1,5} AU(B∩C) represents the all elements of set A and the elements of set (B∩C) which are not present in set A. The common elements are 1,2,3,4,5. AU(B∩C)={1,2,3,4,5}
