Given: 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.
To do: To find the probability that the fish taken out is a male fish.
Solution:
As given, Total number of fishes in the tank$=5( male)+8(female)=13$
Let $E$ be the event that the fish taken out is a male fish.
Number of possible outcomes$=13$
Number of outcomes favorable to $E=5$
$\therefore P(E)=\frac{Number\ of\ favourable\ outcomes}{Total\ number\ of\ possible\ outcomes} = \frac{5}{13}$
Thus, the probability that the fish are taken out is a male fish is $\frac{5}{13}$.
