Question
Sets M and P are defined by
M = { students studying mathematics }
P = { students studying physics }
Describe in words which students belong to the set
(i) M' intersects P'
(ii) ( M intersects P' )'
Answer
(i) Students who take neither Physics nor Maths or both
(ii) Students who are not taking Maths only
There are many ways to describe the required sets in words.
So, the sentences can be phrased differently as long as the required sets are
correct.
To get the required sets, we will first
(a) draw a rectangle to represent the universal set
(b) next we will draw two intersecting circles, circle M for students studying
Maths and circle P for students studying Physics
(c) Next, shade the correct portion for the required set
(d) Finally, we will write the required sets in words, using words as simple as
possible.
