You can put this solution on YOUR website! An electronics store surveyed every 9th customer who came into the store for a week.
Of the 185 people who responded,
76 people watched movies on VHS tapes.
126 people watched movies on DVDs.
23 people watched movies both on VHS tapes and DVDs.
Create a Venn diagram to reflect the above data, label your diagram clearly Use your diagram to answer the following questions here.
--
Draw 2 intersecting circles labeled V= 76 and D= 126
---
The intersection has 23
So V-23 = 53
And D-23 = 103
---------------------
i. Of those surveyed, how many watched only VHS tapes?:::53
----
ii. Of those surveyed, how many watched only DVDs?:::103
-----------
iii. Of those surveyed, how many watched VHS tapes or DVDs, but not both?
:::103+53 = 156
-----------------------
iv. Of those surveyed, how many watched VHS tapes or DVDs, or both?
53 + 103 + 23 = 179
