Question

out of 500 car owners investigated , 400 owend car Aand 200 owend car, B 50 owend both Aand B cars. it is correct? ​

Answer 1

Step-by-step explanation:

In the figure, if AB ǁ CD, EF perpendicular on CD and GED = 114 O, Find the value AGE, GEF and FGE

Answer 2

Answer:

Let U= set of car owners investigated

M= set of persons who owned car A

S= set of persons who owned car B

Then n(u)=500,n(M)=400,n(S)=200 and n(S∩M)=50

∴n(S∪M)=n(S)+n(M)−n(S∩M)

=200+400−50=550

But S∪M⊂⇒n(S∪M)≤n(U)

This is contradiction. So, the given data is incorrect
