How many subscribers belong to the set V U (~O ∩ L)?

749
821
870
954

Answer 27

This is what I have so far:
V=387+67+72=526
O∩L = 84+49=133
526+133=659

that was my guess, buy I know im doing something wrong, I dont have a reference sheet, so Im unsure on how to solve it... :/

Answer 28

yeah i m getting the same answer... we have to take a complement of O

Answer 29

@Mertsj, what do you think, im stumped...

Answer 30

idk, what should I put?

Answer 31

659 doesn't match with any of the options... :(

Answer 32

trust me its really very close to the answer

Answer 33

would it be A? that's the closest one

Answer 34

isnt it funny how the last question always seems the hardest... lol

Answer 35

but yeah, @Mertsj, do you have any idea? did we do the problem correctly or are we missing something?

Answer 36

????

Answer 37

@cshalvey its the one with the link

Answer 38

I think i mite have it, (~O ∩ L) is everything in L but outside of O. That would be the two regions of L with values 295 and 67. When we apply the union operation, we add any regions of V that have not already been included. That would be the regions of 72 and 387 and 49 . Adding, we get 295 + 67 + 72 + 387 + 49. = 870. Does that sound right?

Answer 39

yeah its making logic

Answer 40

Yeah, I think you've got it there - I'm coming up with the same thing...

Answer 41

yap its 870

Answer 42

yay! :) okay thanks you guys I have to go submit it now, ill be back on in a little bit :)
