Question
Let p, q, and r be the following statements. p: The bake sale is on Thursday. q: Diane is making cupcakes. r: Diane is using the mixer. For each argument, use the slider to select the symbolic form. Then determine whether the argument is valid. Argument (a) The bake sale is on Thursday or Diane is making cupcakes. The bake sale is not on Thursday. Therefore, Diane is making cupcakes. (b) If the bake sale is on Thursday, then Diane is making cupcakes. The bake sale is not on Thursday. Therefore, Diane is not making cupcakes. Symbolic Form (a) _ (b) _ Is the argument valid? (a) Yes or No (b) Yes or No
