100 people who were surveyed and asked the question: ``Is fuchsia kinda pink, or purply?'' Of them, 60 believe that fuchsia is ``kinda pink'' and 27 believe it is both ``kinda pink,'' and also ``purply.'' Another 17 think that fuchsia is neither ``kinda pink'' nor ``purply.''
How many of those 100 people believe that fuchsia is ``purply''?
I think Chris MAY have answered your question.....but you did not ask for #people who think 'purply ONLY' , you asked for 'purply'
'purply' would include the 'purply-only' 23 AND the 'kinda-pink and Purply' 27 23 +27 = 50 think purply. This is consistent with your statement that 60 people think it is kinda pink which includes the 27 who thought BOTH.
(purply ONLY = 23 , but that was not what was asked in your question) Thanx, Chris!
