The veterinarian decides to randomly choose in which order to see the pets. If one pet is chosen for the first appt and another pet is chosen for the second appt, construct a tree diagram or a list a sample space of all the possible outcomes of which pets will receive the first and second appt. Determine the probability that one dog and one cat will receive the first two appt with the veterinarian.
