Answer: 66.7% error
Step-by-step explanation:
The equation [tex]\frac{abs(E-A)}{E}[/tex] * 100%, where E is the expected value and a is the actual value (abs just means if the value is negative make it positive), and we have an expected value of 6, and an actual of 10, so plugging in we have abs((6)-(10)/6) * 100%, which comes out to be 66.7% error.
