1. The problem asks for the average (mean) number of toys in 6 boxes with counts: 4, 10, 7, 0, 4, 5. 2. The formula for the average (mean) is: $$\text{Mean} = \frac{\text{Sum of all values}}{\text{Number of values}}$$ 3. Calculate the sum of the numbers: $$4 + 10 + 7 + 0 + 4 + 5 = 30$$ 4. Count the number of boxes: $$6$$ 5. Apply the formula: $$\text{Mean} = \frac{30}{6} = 5$$ 6. Therefore, the average number of toys in the boxes is 5. The correct answer is option A: 5.
