    Ramesh buys a fish from a shop for his aquarium. The shopkeeper takes out one fish at random a tank containing 5 male fish and 9 female fish. Then, the probability that the fish taken out is a male fish, is

    A) \[\frac{5}{13}\]

    B) \[\frac{5}{14}\]

    C) \[\frac{6}{13}\]

    D) \[\frac{7}{13}\]

    Correct Answer: B

    Solution :

    There are 14 = (5 + 9) fish out of which one can be chosen in 14 ways. \[\therefore \]Total numbers of possible outcomes =14 There are 5 male fish out of which one male fish can be chosen in 5 ways. \[\therefore \]Favourable number of elementary events = 5 Hence, required probability \[=\frac{5}{14}\]
