## Spartan_Of_Ares 2 years ago A news agent conducted a survey among travel magazine subscribers of a town and found that there was circulation of only three travel magazines. He made the Venn diagram below to show the number of subscribers to each of the three magazines: Leisure, Outbound, and Vacations. How many subscribers belong to the set V U (~O ∩ L)?

@jim_thompson5910 can you help me with some problems?

3. jim_thompson5910

Do you know how to visually find ~O ∩ L ?

4. Spartan_Of_Ares

finding what they have in common?

5. jim_thompson5910

yes, what do ~O and L have in common

6. Spartan_Of_Ares

49 and 84?

7. jim_thompson5910

What numbers are a) Not in set O and b) in set L

8. Spartan_Of_Ares

295

9. jim_thompson5910

what else

10. Spartan_Of_Ares

67

11. jim_thompson5910

so those numbers are in the set ~O ∩ L ie they are in L but NOT in O

12. jim_thompson5910

now add on any numbers found in set V

13. Spartan_Of_Ares

@jim_thompson5910 sorry my computer crashed

14. jim_thompson5910

that's ok

15. jim_thompson5910

so did you get the answer?

16. Spartan_Of_Ares

so my answer would be 295 67 and 387

17. jim_thompson5910

what else is in V

18. Spartan_Of_Ares

72 and 49?

19. jim_thompson5910

yep, so the numbers 295, 67, 387, 72, 49 are in the set V U (~O ∩ L)

20. jim_thompson5910

add up all of these numbers to figure out how many subscribers belong to the set V U (~O ∩ L)

21. Spartan_Of_Ares

870?

22. Spartan_Of_Ares
