Question 2 -

For the arguments that you formulated in symbols, determine whether each is valid or not. Note: Remember you can determine if it is valid or not either by using Rules of Inference or using truth table. If using Rules of inference, you need to mention which rules you used. If using truth table, you need to show that whenever the hypotheses are true, the conclusion is true.

2. Let p, q, and r be the following propositions: p: I study hard. g: I get A's. r I get rich. Formulate the arguments symbolically a. If I study hard, then I get A's. I study hard. .I get A's. b. If I study hard, then I get A's. If I don't get rich, then I don't get A's. Iget rich. c. I study hard if and only if I get rich. I get rich. I study hard d. If I study hard or I get rich, then I get A's. I get A's. If I don't study hard, then I get rich e. If I study hard, then I get A's or I get rich. I don't get A's and I don't get rich. . I don't study hard
