\begin{tabular}{|l|c|c|c|c|}
\hline & A & B & C & D \\
\hline Order Accurate & 329 & 280 & 249 & 145 \\
\hline Order Not Accurate & 34 & 55 & 32 & 12 \\

If one order is selected, find the probability of getting an order that is not accurate.
The probability of getting an order that is not accurate is (Round to three decimal places as needed.)

Check answer

Step 1 ：Given the data in the table, we can see that the total number of accurate orders is 329 + 280 + 249 + 145 = 1003 and the total number of inaccurate orders is 34 + 55 + 32 + 12 = 133. Therefore, the total number of orders is 1003 + 133 = 1136.

Step 2 ：To find the probability of getting an order that is not accurate, we need to divide the total number of inaccurate orders by the total number of orders. So, the probability is \(\frac{133}{1136}\).

Step 3 ：Using a calculator, we find that \(\frac{133}{1136}\) is approximately 0.117.

Step 4 ：Final Answer: The probability of getting an order that is not accurate is \(\boxed{0.117}\).
