12.Write expressions for the following in Predicate Logic (defining your predi-cates) and then determine if the inference is valid. If it is, you must indicate the rulesused. If it is invalid you must indicate why.Doug, a student in this class, knows how to program in Java. Everyone who knows howto program in Java can get a high-paying job. Therefore, someone in this class can geta high-paying job.

Directions: Translate each of the following statements into the language ofsentential logic. Use the suggested abbreviations (capitalized words), if provided;otherwise, devise an abbreviation scheme of your own. In each case, write downwhat atomic statement each letter stands for, making sure it is a completesentence. Letters should stand for positively stated sentences, not negativelystated ones; for example, the negative sentence ‘I am not hungry’ should besymbolized as ‘~H’ using ‘H’ to stand for ‘I am hungry’. questiona) Neither JAY nor KAY is able to attend the meeting. b) Although I have been here a LONG time, I am neither TIRED nor BORED.

State our definition of “valid inference” and then explain how to use a truth table to test the validity of an inference in zeroth-order logic.
A local health clinic often makes this statement to its patients. If you get a flu shot, then you won't get the flu thus winter. (a) Statements p and q are defined as follows. p: You get a flu shot. q: You get the flu this winter. Write the clinic's statement in symbolic form using p and q Symbolic form: __ (b) Suppose the following situation occurred. You got a flu shot. During winter, you got flu. Complete the table to determine the truth of the clinic's statement in this situation. Use T for true and F for false.
I. Cite two arguments you've heard of lately. Prove the argument if it's logically correct by: 1. Translating to symbolic logic. 2. Determining the rules of inference followed (if there's any). a. If the argument is logically incorrect, state the error made, or the changes that needs to be done. Example: Propositional Logic Symbolic Logic E → W Observed Rules of Inference 1. "If you send me an e-mail message, then I will finish writing the program." "If you do not send me an e-mail message, then I will go to sleep early." "I did not finish writing the program." Therefore, "I will go to sleep early." Modus Tollens ~E → S Modus Ponens
Propositional wffs and truth tables belong to a system of two-valued logic because everything has one of two values, F or T, which we can think of as 0 or 1. In fuzzy logic, or many-valued logic, statement letters are assigned values in a range between 0 and 1 to reflect some “probability” to which they are false or true. A statement letter with a truth value of 0.9 is “mostly true” or “has a high probability of being true” while a statement letter with a truth value of 0.05 “has a very high probability of being false.” Fuzzy logic is used to manage decisions in many imprecise situations such as robotics, manufacturing, or instrument control. Truth values for compound statements are determined as follows.A′ has the truth value 1 − A.A Λ B has the truth value that is the minimum of the values of A and of B.A ∨ B has the truth value that is the maximum of the values of A and B.a. Explain why these are reasonable assignments for the truth values of A′, A Λ B, and A ∨ B.Suppose the…
