Hi guyes,
Yes Plato, you are right here:
Set U = {3,4,5,6,7,8,9,.....18}
Set A = {5,6,7,8,9,..........16}
Set P = P's power c
But problems now is that, what would be the elements of Set P's power c
and if i am not wrong i should take for question-3, ={Number divisible by 4}
from universal set or not ?
So, if I am right then answer to question-3 would be {4,8,12,16}
Thanks for your guidance and support.
