Step 1:  Calculate the total number of fishes inside the aquarium

                    Male fish = 5

                Female fish = 8

                    Total fish = 5 + 8 = 13


Step 2:  Find the probability of getting the male fish

            Total male fish in the aquarium = 5

            So, favourable outcomes = 5


      Then, the probability that the fish taken out is a male fish = \frac{\text{number of male fish}}{\text{total number of fishes}}


                                                                                                 = \frac{5}{13}
