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 the given 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 male fishes + Number of female fishes
= 5 + 8 = 13

$\text{Probability}\ \text{ of}\ \text{ getting}\ \text{ a }\ \text{male}\ \text{ fish}=\frac{\text{Number}\ \text{ of} \ \text{favourable}\ \text{ outcomes}}{\text{Number}\ \text{ of }\ \text{total }\ \text{possible} \ \text{outcomes}}$
$=\frac{5}{13}$
