wassup:
The question is shade AUB'. Why is the pointed part shaded? (See below)

@d!_†oX!©:
dude cuz di is A union B'
if it was A intersection B' then we wouldn't shade that part!!

nid404:

B'  is everything not in B...which includes A and the rest of the universal set. and it is union A and A consists of the shaded oart also

wassup:
