I would go with D, unless I'm misinterpreting the first statement.
Prop Memphis does not win contest = 1 - (prob they win)
Statement 1 tells us that each city has a 7/8 chance of not winning - therefore Memphis has a 7/8 prob of not winning the contest - answer it right there.
Statement 2 tells us they have a 1/8 chance of winning - 1-(1/8) = chance of not winning, also 7/8.
