Hi guys,

I recently came across an overlapping set question which I couldn't answer (cant remember the whole question with the name of the variables, only the numbers)

56% who eat hamburgs also eat fries
44% who eat fries also eat hamburgs
22% did eat hamburgs and no fries
x% did eat fries and no hamburgs

In order to find x%; can i assume that the overlapp is 34% (56-22%) so that x% is 10% (44-34%)? Is my reasoning correct?

Thanks!
