Computer Methods - Math Problem suitS will be computed by finding T - S, soS = (1, 1), (2, 1), (2, 2) Question 21. a) Using the spare-time activity propositions h it is humid c it is cloudyand d it is rain downexpress the following logical musings in good English.i) (hc)rii) (rh)c b) Assuming and S is a set of lectures and the and the predicatesL(x) x is a subscriberand A(x) x is conversewrite the following sentences in symbolic formi) Larry is an articulate lecturer.ii) There is a lecturer who is not articulate.iii) Not perpetuallyy lecturer is articulate.What is the relationship between predicates (ii) and (iii)c) Determine the truth table for (pq)(pq) State whether this expression is contingency, a contradiction or a tautology. Solution a)i) (hc)rthe atmosphere is humid cloudy and it is not raining ii) (rh)c if atmosphere is raining or humid then atmosphere is cloudy.b)(i)Larry is an articulate lecturer.L(Larry) A(Larry)(ii) There is a lecturer who is not articulate.To so lve this we will use the concept of universal quantifiers $(x)Which factor that a statement is confessedly for all values of x. Now the statement in symbolic form is(x)L(x) A(x)Which means that it is not uncoiled that all the lecturers are articulate. So in this sense this predicate describes that there are most(prenominal) lecturers who are not articulate (iii)Not every lecturer is articulate.(x)L(x) A(x)The relationship between furthest 2 predicates is that these define same thing i.e. Not every lecturer is articulate does not ever means that All the lecturer are not articulate it could mean...And all the points that are not common in any set are placed in circles where no intersection is occurring.The relationship between last two predicates is that these define same thing i.e. Not every lecturer is articulate does not ever means that All the lecturer are not articulate it could mean that There are some lecturers who are not articulate so we tail assembly not use univer sal quantifiers for this predicate so it means that Not every lecture is articulate but there are some that can be articulate so in this sense of interpretation last two predicates are same.
