DQ SETS:MYSTERY BEINGS

One hundred sixty people were surveyed and asked if they believed in UFOs, ghosts, and Bigfoot.

42 believed in UFOs 45 believed in ghosts

21 believed in Bigfoot 11 believed in UFOs and ghosts

6 believed in ghosts and Bigfoot
4 believed in UFOs and Bigfoot

2 believed in all three

Put 2 in the middle for all that believed in beings.
First of what I did is subtract 2 with 11 of those who believed in UFOS & GHOSTS. Then repeated it for all the other problems that would add up to the others in the diagram.
