Revised: 89 Believe in at least one thing, 71 neither
This is simple to self correct, I got the initial answer wrong by only adding the people who ONLY believed in one thing UFO 29+Bigfoot 13+ Ghosts 30, instead I shouldve also added all the people who believe in more than one 2+2+9+4 which wouldve given me 89 people who believed in at least one thing, to that we substract from the total people surveyed (160) which gives us 71 non believers. Its all in the details!
