An electronics store surveyed every 8th customer who came into the store for a week.
Of the 380 people who responded,

185 people watched movies on VHS tapes.
251 people watched movies on DVDs.
72 people watched movies both on VHS tapes and DVDs.

i. Of those surveyed, how many watched only VHS tapes?
ii. Of those surveyed, how many watched only DVDs?
iii. Of those surveyed, how many watched VHS tapes or DVDs, but not both?
iv. Of those surveyed, how many watched VHS tapes or DVDs, or both?

(I'm not sure how if this is a trick question or what, please help...)

Try drawing a diagram. It's not a trick question.
