Shalu buys a fish from a shop for her aquarium. The shopkeeper takes out one fish at random from a tank containing 5 male fish and 8 female fish. What is the probability that the fish taken out is a male fish?

Answer

To find the probability that the fish taken out is a male fish, we can follow these steps:

### Step 1: Identify the number of male and female fish
In the tank, there are:
- Male fish = 5
- Female fish = 8

### Step 2: Calculate the total number of fish
To find the total number of fish in the tank, we add the number of male fish and female fish together:
\[ \text{Total fish} = \text{Number of male fish} + \text{Number of female fish} = 5 + 8 = 13 \]

### Step 3: Determine the number of favorable outcomes
The favorable outcomes for our event (selecting a male fish) is simply the number of male fish:
\[ \text{Favorable outcomes} = \text{Number of male fish} = 5 \]

### Step 4: Calculate the probability
The probability of selecting a male fish can be calculated using the formula:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{5}{13} \]

### Final Answer
Thus, the probability that the fish taken out is a male fish is:
\[ \frac{5}{13} \]
