best done with a Venn diagram.
Two intersecting circles, one for Democrat, the other for Business major
enter 5 in the intersection of the two circles
enter 29-5 or 24 in the "Democrat only" part of the Venn
enter 11-5 or 6 in the business only part
in the circles you now have 24 + 5 + 6 or 35 entered.
Where do the remainders of the total of 50 go ??
