Given that P is the set of all prime numbers between 0 and 10, and Q is the set of all odd numbers between 0 and 10. Find the union of elements in P that are not in Q and the elements in Q that are not in P.
- {2, 9}
- { 9}
- {1, 9}
-
{1, 2, 9}
The correct answer is: D
Explanation
P = {Primes numbers b/w 0 and 10} = { 2, 3, 5, 7}
Q = { Odd numbers b/w 0 and 10} = {1, 3, 5, 7, 9}
Let W = { Union of elements in P not in Q and elements in Q not in P} = {1, 2, 9}
