Let P and Q be the following statements. p: The shirt is purple.q: The shirt shows school spirit.Consider this argument.Premise 1: If the shirt is purple, then the shirt shows school spiritPremise 2: The shirt shows school spirit.Conclusion: Therefore, the shirt is purple.(a) Write the argument in symbolic form.Premise 1:rPremise 2:ロヘロロvロConclusion:ロ→ロ(b) Is the argument valid?O YesO NoDEC10

Valid argument: An argument is valid if and only if it is necessary that if all of the premises are true, then the conclusion is true; if all the premises are true, then the conclusion must be true. We have given p: The shirt is purple and q: The shirt shows school spirit. Premise 1: If the shirt is purple, then the shirt shows school spirit. Premise 2: The shirt shows school spirit. _________________________________________ Conclusion: Therefore, the shirt is purple.a) The given statements in symbolic form: Premise 1: p → q Premise 2: p __________________ Conclusion: ∴ p b) Since both the premises are true hence the conclusion is true. Therefore, the given statement is valid. Answer: a) The given statements in symbolic form: Premise 1: p → q Premise 2: p __________________ Conclusion: ∴ p b) yes.
