Answer

Answer:

The experimental probability is greater than the theoretical probability by more than 2%.

Explanation:

Step1: Calculate theoretical probability

The theoretical probability of rolling a 1 on an 8 - sided die is $P_{theoretical}=\frac{1}{8}=0.125 = 12.5%$.

Step2: Calculate experimental probability

4 out of 48 customers used a coupon. So $P_{experimental}=\frac{4}{48}=\frac{1}{12}\approx0.0833 = 8.33%$.

Step3: Find the difference

The difference is $|P_{experimental}-P_{theoretical}|=|8.33% - 12.5%|=4.17%>2%$. Since $8.33%<12.5%$, the experimental probability is less than the theoretical probability by more than 2%.
