Question

22. Suppose U = {1,2,3,4,5,6,7,8} is the universal set and P = {2,4,6,8}. What is P'?
24. Suppose U = {1,2} and T = {1}. What is T'?

Answer 1

OK !
look P' have the things are in U and are not in P .
For example : 1 is in U but is not in P .
we say P' Complementarity for P .
and say U the M (Mother) .
Look at this :
If :
M={1,2,3,4,5,6,7}
A={1,2,3}
A'={4,5,6,7}
ok ?:)
Got it ?;)
