Ex 15.1, 11 Gopi buys a fish from a shop for his aquarium. The shopkeeper takes out one fish at random from a tank containing 5 male fish and 8 female fish (see the given figure). What is the probability that the fish taken out is a male fish? Total number of fishes in a tank = Number of male fishes + Number of female fishes = 5 + 8 = 13 Number of male fishes = 5 Probability of getting a male fish = (ππ’ππππ ππ ππππ πππ βππ )/(πππ‘ππ ππ’ππππ ππ πππ βππ ) = 5/13
