Step-by-step explanation:
P = { odd number less than 10 }
= { 1 , 3 , 5 , 7 , 9 }
Q = { even number less than 5 }
= { 2 , 4 }
PQ = ??
Now ,
PQ = { 1 , 3 , 5 , 7 , 9 } × { 2 , 4 }
= { 2 ,6, 10 ,14 ,18 ,4 , 12 , 20 , 28 , 36 }
= { 2,4,6,10,12,14,18,20,28,36 }
I think this is a answer... Thank you ☺️☺️☺️☺️
