Question

in a survey of 350 students of a school 200 like pokhara 220 like chitwan and 120 liked both places then find number of students who liked neither or two places show the venn diagram​

Answer 1

Answer:

Let the students who like pokhara be p and chitwan be c respectively .

Step-by-step explanation:

n(U)=350

n(P)=200

n(C)=220

n(PnC)=120

n(PUC) complement=?

Now,

n(PUC)= n(P)+n(C)-n(PnC)

=200+220-120

=300

n(PUC)complement =n(U)-n(PUC)

=350-300 =50
