प्रश्न
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 Figure). What is the probability that the fish taken out is a male fish?
उत्तर
Total number of fishes in a tank
Number of female fishes = 8
Number of male fishes = 5 + 8 = 13
∴ Total number of outcome = 13
For a male fish
Number of favourable outcomes = 5
Probability of getting a male fish = `"Number of favourable outcomes"/"total Number of outcomes"`
= `5/13`
