Discussion Question 1 by Michael Rivera

UFO and Bigfoot calculation:
We know that 4 people believed in bigfoot and the UFO. Therfore, 2+b= 4. In this case, I substacted 4-2 to find b=2

UFO and Ghost calculation:
We know that 11 poeple believed in the UFO and Ghost. Therefore, 2+c= 11. In this case, I subtracted, 11 -2 to find c= 9

Bigfoot and Ghosts calculation:
We know that 6 poeple believed in Bigfoot and the Ghost. Therefore, 2+d=6. In this case, I subtracted, 6 -2 to find c= 4

To find all the other indiviual values in each circle, I added everyone who believed in all three, and the ones that believed in both. Then substracted from the original numbers at the discussion questions

29+2+2+9+13+4+30= 89

89 people believed at least in one of the each things.


E.g:

UFO calculation:

2+2+9= 13 (inner part)
We know 42 people belived in UFO's. Therefore, 42-13 = 29.
29 people believe in UFO's.

29+2+2+9=42

71 believe in none

Calculation:
add all the values in the venn diagram and substract by the total 160.

29+13+30+2+2+4+9= 89
160-89=71

72 people believed in at least one of these things:

29+13+30=72
