Study the following diagram and answer questions based on it. The colour preferences of children are given (White = rectangle, Black = circle, Brown = oval).
How many children like both brown and white but not black?
None
The region 'brown and white but NOT black' is the intersection of the oval (Brown) and rectangle (White) that lies OUTSIDE the circle (Black).
From the diagram, this specific region contains no children.
So the count is None (0).
Hence, None.
