Answer:
Number of people surveyed believed in at least one of these things = 83
Step-by-step explanation:
Given,
Total number of people, n(T) = 160
number of people believe in UFOs, n(U) = 42
number of people believe in ghost, n(G) = 45
number of people believe in Bigfoot, n(B) =21
number of people believe in UFOs and ghost, n(U ∩ G) = 11
number of people believe in Bigfoot and ghost, n(B ∩ G) = 6
number of people believe in UFOs and Bigfoot, n(U ∩ B) = 4
number of people who believe in all, n(U ∩ G ∩ B) = 2
We have asked to draw the Venn diagram and to calculate the number people surveyed believed in at least one of these things .
So, according to Venn diagram,
Number of people surveyed believed in at least one of these things = 25+11+4+2+26+9+6 = 83
Number of people surveyed believed in at least one of these things = 83
