If T = {prime numbers} and M = {odd numbers} are subsets of \(\mu\) = {x : 0 < x≤10} and x is an integer, find (T\(^{\prime}\) n M\(^{\prime}\)).
- A. {4, 6, 8, 10}
- B. {1. 4, 6, 8, 10}
- C. {1, 2, 4, 6, 8, 10}
- D. {1, 2, 3, 5, 7, 8, 9}
Correct Answer: A. {4, 6, 8, 10}
Explanation
T = {2, 3, 5, 7}
M = {1, 3, 5, 7, 9}
\(\mu\) = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
T\(^{\prime}\) = = {1, 4, 6, 8, 9, 10}
M\(^{\prime}\) = {2, 4, 6, 8, 10}
(T\(^{\prime}\) \(\cap\) M\(^{\prime}\)) = {4, 6, 8, 10}
