1. Conclusions
Consider the following set of premises:
(1) If it is not to0 cold and if it doesn't rain, then I will go to Zulu.
(2) If I go to Zulu, then I will get a coconut.
(3) I did not get a coconut and it doesn't rain.
Use rules of inference to show that these premises imply the conclusion "It is too
cold.". List the name of each rule of inference you use.
2. Even and Odd
(a)
Use a direct proof to show that the sum of two odd integers is even.
Use an indirect proof by contrapositive to prove that for integers m
(b)
and n, if mn is even, then m is even or n is even.
(c)
Prove that there is no largest odd integer.
