5. (Theoretical Probability MC) A set of 3 cards, spelling the word ADD, are placed face down on the table. Determine P(A, A) if two cards are randomly selected wit

The word ADD has 3 letters: A, D, D. The total number of possible outcomes when selecting two cards is 3. The number of ways to select two 'A' cards is 0, as there is only one 'A'. Therefore, the probability of selecting two 'A' cards is 0/3.

P(A, A) = 0/3 = 0
