if P = {x:x is odd, \(-1 < x \leq 20\)} and Q is {y:y is prime, \(-2 < y \leq 25\), find P \(\cap\) Q
A
{3,5,7,11,17,19}
B
{3,5,11,13,17,19}
C
{3,5,7,11,13,17,19}
D
{2,3,5,7,11,13,17,19}
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
P = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19}
Q = {-1, 3, 5, 7, 11, 13, 17, 19, 23}
P \(\cap\) Q = {3, 5, 7, 11, 13, 17, 19}
