Given that ξ = {1, 2, 3, . . . . . . ,10}, P= (x : x is prime) and Q = {y : y is odd}, find P

^{l}∩Q-
**A.**

{2} -
**B.**

{1,9} -
**C.**

{315.7} -
**D.**

{4, 6, 8, 10}

##### Correct Answer: Option B

##### Explanation

ξ = {1, 2, 3, . . . . . . ,10}, P= (2, 3, 5, 7) and Q = {1, 3, 5, 9},

P^{l}∩Q = {1, 4, 6, 8, 9, 10}∩{1, 3, 5, 7, 9} = {1, 9}
