Consider the Venn diagram below.
The total number of shoppers surveyed is, <em>N</em> = 428.
Number of shoppers who made a purchase, <em>n</em> (P) = 216
Number of shoppers who were satisfied with the service they received,
<em>n</em> (S) = 294
Number of shoppers who made a purchase but were not satisfied with the service, = 47
(a)
The number of shoppers who made a purchase and were satisfied with the service = <em>n</em> (S ∩ P)
(b)
The numbers of shoppers who made a purchase or were satisfied with the service = <em>n</em> (P ∪ S)
(c)
The numbers of shoppers who were satisfied with the service but did not make a purchase =
(d)
The number of shoppers who were not satisfied and did not make a purchase =
In a coincidental system both equations are the same. I try to transform one equation into the other:
