Question

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?

Answer 1

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`
