30=17+15+20-Both-2*-all 30=52-Both-2*all 22=Both+2All 22-Both/2=All We want to min All, so pick the highest value of both - in this case 22, which leads to 0.
Oh perfect! I was wondering if we could use this formula - but didn’t know how. How do you maximise both?HenryHai
and both also, can you specify it please ? thank you
you’re right - all is the the overlap of all three sets. Both is the overlap of any two sets (minus the overlap of all three).Dumsy_1711

like I understand in this case the value will have to be 22 to get x(min) =0. But if we had to find the maximum value of n(Exactly two sets) given total = 30 ; n(A) = 15 ; n(B) = 17; and n(C) = 20
