Given that ξ = {1, 2, 3, . . . . . . ,10}, P= (x : x is prime) and Q = {y : y is odd}, find P'∩Q
A
{2}
B
{1,9}
C
{315.7}
D
{4, 6, 8, 10}
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
ξ = {1, 2, 3, . . . . . . ,10}, P = (2, 3, 5, 7) and Q = {1, 3, 5, 7, 9},
P'∩Q = {1, 4, 6, 8, 9, 10}∩{1, 3, 5, 7, 9} = {1, 9}
