How Many People Believed In At Lest One of These Things?
Based on my work I have found that at least 113 people believed in at least one of these things. Taking Into Account that there are three elements in the set and subtracting each total amount by 2 and then combinding it all it equals 119.
42-2=40
21-2=19
6-2=4
45-2=43
11-2=9
4-2=2
2-2=0
119
Also Adding (42+11+52+21=119)
