At the Philadelphia Zoo, there are 2 types of animals at the Water is Life exhibit: giant otter, red panda. The animals each perform one of these 5 actions: eating, sleeping, rolling, swimming, resting. I saw two animals at the exhibit and one of them was a red panda swimming. Assuming that it is equally likely for me to have seen any combination of species and actions (including duplicates), what is the probability that both animals were swimming?
