Question

Symbolize the following argument, and test it for validity. If valid, construct a deduction;
if invalid, assign truth values that show that the premises can be true while the conclusion is false. Use these letters: D = The drought will continue; S = We get an early storm;
M = Managers of the ski areas will be happy; F = There will be great fire danger next year.
The drought will continue if we dont get a storm. If we do get a storm, the managers of the ski areas will be happy. Since well either get a storm or we wont, it follows that either the drought will continue or the ski area managers will be happy.
