Problems 87 and 88 refer to the data in the following table, obtained from a random survey of 1,000 residents of a state. The participants were asked their political affiliations and their preferences in an upcoming election. (In the table, D = Democrat, R = Republican, and U = Unaffiliated.)

If a state resident is selected at random, what is the (empirical) probability that the resident is

(A) A Democrat or prefers candidate B? What are the odds for this event?

(B) Not a Democrat and has no preference? What are the odds against this event?
