p (B-CB-BM-2CMB) = 30/100 = 3/10

100 = C+M+B-CM-CB-BM-2CMB
100 = 50+40+B-20-CB-BM-2CMB
B-CB-BM-2CMB = 100-90+20
B-CB-BM-2CMB = 30

yeah use Venn diagram...

no cake or muffin = 100 - (cake + muffin - both)
= 100 - (50 + 40 - 20)
= 30

when you subtract 20, i believe it should be subtracting 40... since the subtraction should be counted twice.
