question 77

Short Answer

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.
Unless an early storm moves in,the drought will continue,and there will be great danger of fire next year.But the drought is not going to continue.Therefore,there will not be a great danger of fire next year.
