# 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 Fig. 15.4). What is the probability that the fish taken out is a male fish?

**Solution:**

We know that,

Probability of = Number of possible outcomes/Total number of favorable outcomes

Number of male fish = 5

Number of female fish = 8

Total number of fishes = 5 + 8 = 13

The probability that the fish taken out is a male fish = Number of male fish/Total number of fishes

= 5/13

Thus, the probability that the fish that are taken out is a male fish, is 5/13.
