Step-by-step explanation:
Let the event of people who believe that fuchsia is pink = A
Let the event of people who believe that fuchsia is purply = B
- Since 100 people were surveyed, the Universal Set =100
- 60 believe that fuchsia is ``kinda pink'', n(A)=60
- 27 believe it is both ``kinda pink,'' and also ``purply.'':
- 17 think that fuchsia is neither ``kinda pink'' nor ``purply.
We want to determine the number of those who believe that fuchsia is ``purply'', n(B).
In set theory, we have:
Therefore, the number of those who believe that fuchsia is ``purply'' is 50.
