If X = {x : x < 7} and Y = {y : y is a factor of 24} are subsets of mu = {1, 2, 3, ..., 10}, find X n Y.
- A. {2,3,4,6}
- B. {1,2,3,4,6}Correct
- C. {2,3,4,6,8}
- D. {1,2,3,4,6,8}
Explanation
X = {1,2,3,4,5,6}, Y = {1,2,3,4,6,8} (factors of 24 within the universal set). Since Y is a subset of mu, X n Y = {1,2,3,4,6}.
