Calculate the Average: Finding Mean of 17, 4, and 12

To solve this problem, we'll follow these steps:

• Step 1: Calculate the sum of the given numbers.
• Step 2: Determine how many numbers are in the set.
• Step 3: Use the average formula to find the solution.

Now, let's work through each step:
Step 1: Add the numbers together:
$17 + 4 + 12 = 33$.
Step 2: Count the numbers: There are 3 numbers.
Step 3: Calculate the average using the formula:
$\text{Average} = \frac{33}{3} = 11$

Therefore, the average of the numbers 17, 4, and 12 is $11$.
