In a class of 50 students, 29 are Democrats, 11 are business majors, and 5 of the business majors are Democrats. If one student is randomly selected from the class, find the probability of choosing: (a) Democrat who is not a business major. (b) A student who is neither a Democrat nor a business major.
a. 11/25 b. 4/10
a. 12/25 b. 3/10
a. 9/25 b. 6/10
a. 7/25 b. 5/10

Answer 1

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 ??

You now know where everybody fits in, and should be able
