22% only own a PS3
42 plus 36=78 -> no margin for people who own both. (makes more sense now?) |
42% of PS3 owners own a Wii (this does not exclude that they own a X360)
36% of PS3 owners own a X360 (this does not exclude that they own a Wii)
42 plus 36 = 78% of PS3 owners who own one or both of the other consoles
22 plus 78 = 100%.
They do not state how many own all 3, but we can conclude that it is below 36% of all PS3 owners own all 3 consoles. If we looked at Wii owners and X360 owners we might come to a slightly lower % who own all 3 systems.
It works out perfectly. I didn't copy NPD data for Wii owners or X360 owners though.
