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.
A
{2, 9}
B
{ 9}
C
{1, 9}
D
{1, 2, 9}
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
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}
