Find Number Groups with Mean = 4: Average Value Problem

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

• Calculate the average for each group of numbers provided in the choices.
• Identify the group whose average equals 4.

Let's apply these steps to each choice:

Choice 1: $2, 2$

$\text{Sum} = 2 + 2 = 4$
$\text{Count} = 2$
$\text{Average} = \frac{4}{2} = 2$

Choice 2: $6, 3, 3$

$\text{Sum} = 6 + 3 + 3 = 12$
$\text{Count} = 3$
$\text{Average} = \frac{12}{3} = 4$

Choice 3: $6, 4, 5$

$\text{Sum} = 6 + 4 + 5 = 15$
$\text{Count} = 3$
$\text{Average} = \frac{15}{3} = 5$

Choice 4: $4, 0, 0$

$\text{Sum} = 4 + 0 + 0 = 4$
$\text{Count} = 3$
$\text{Average} = \frac{4}{3} \approx 1.33$

Upon examining these calculations, the group $6, 3, 3$ (Choice 2) has an average of 4, which satisfies the condition given in the problem.

Therefore, the solution to the problem is $6, 3, 3$.
