The probability of getting an order that is not accurate is approximately 0.095 or 9.5%.
To find the probability of getting an order that is not accurate, you need to use the formula:
Probability=

In this case, the number of favorable outcomes is the sum of "Order Not Accurate" values in the table, and the total number of possible outcomes is the sum of all values in the table.
Let's calculate it:
Number of favorable outcomes (Order Not Accurate): 58 + 40 = 98
Total number of possible outcomes: 338 + 33 + 279 + 239 + 120 + 20 = 1029
Now, plug these values into the formula:
Probability=

Now, calculate the fraction and round to three decimal places:
Probability≈0.095
So, the probability of getting an order that is not accurate is approximately 0.095 or 9.5%.
