1.	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» Number of male fish = 5 Number of female fish = 8 Total number of fish = 5 m + 8 f = 13 fishes. ∴ Number of total outcomes in taking a fish at random from the aquarium =13. Number of male fish = 5 ∴ Number of outcomes favourable to male fish = 5. ∴ The probability of taking a male fish = \(\frac{No.\,of\,favourable\,outcomes}{Total\,no.\,of\,outcomes}\) = 5/18 = 0.38

Answer»

Number of male fish = 5

Number of female fish = 8

Total number of fish = 5 m + 8 f = 13 fishes.

∴ Number of total outcomes in taking a fish at random from the aquarium =13.

Number of male fish = 5

∴ Number of outcomes favourable to male fish = 5.

∴ The probability of taking a male fish =

\(\frac{No.\,of\,favourable\,outcomes}{Total\,no.\,of\,outcomes}\)

= 5/18

= 0.38
