Problem 1899

Translate the argument into symbolic form. Then determine whether the argument is valid or invalid. You may use a truth table or, if applicable, compare the argument's symbolic form to a standard valid or invalid form.
You drew a three, or you have two pairs. Today you do not have two pairs. $\therefore$ Today you drew a three. (i) Click the icon to view tables of standard valid and invalid forms of arguments.
Let p represent "Today you drew a three.," and let q represent "Today you have two pairs." Select the correct choice below and fill in the answer box with the symbolic form of the argument. (Type the terms of your expression in the same order as they appear in the original expression.) A. The argument is valid. In symbolic form the argument is $\square$ B. The argument is invalid. In symbolic form the argument is $\square$
