There are three sets defined: S is the set of all integers, P is the set of prime numbers, and Q is also the set of prime numbers. P and Q are subsets of S as all prime numbers are integers. The relationship between the sets is that P and Q are subsets of S.

Traffic officers carry out checks on
motorists. The result is 25 person
have SIM A and 30 have SIM C , 17
have both, and 12 don’t have both,
how many were checked?

3. S
44
44 students in class
30 liked Math's
26 liked Physics
3 unlike both
Who like both lesson?
Answer: 30-X+X+26-X+3=44
30+26-X+3=44
56-X+3=44
X=15

Math’s Physics
There is 44 students in class, there are
30 students liked math and 26 students
like physics, If 3 students doesn’t like
both of them, how many like both of
them?

4. S Pop Classic
10
In the event the survey of predilection
of music data showed in that class III,
15 students love pop music and 20
students fond of classical music. If 5
people love pop music and classical
as well as 10 people are not fond of
pop music and classical music, how
many students are in year III?
Pop =15
Classic =20
Both =5
