We are required to find AnU, In words A intersection U

This means we are to find the elements that are common in A and U


A\text{ = }\lbrace3.5.6.7\rbrace


U\text{ =}\lbrace1,2,3,4,5,6,7,8,9\rbrace

The common elements are 3,5,6 and 7. They are both in A and U

Hence,


AnU=\lbrace3,5,6,7\rbrace
