The given data depicts the number of food orders from four different outlets under two categories, accurate order and inaccurate order, in a tabulated form.

The probability of an event E has the following expression:

$P\left(E\right)=\frac{\text{Number}\text{of}\text{favorable}\text{outcomes}}{\text{Total}\text{number}\text{of}\text{outcomes}}$

The following table shows all the subtotals and the grand total.

Let E be the event of getting an inaccurate food order.

The total number of inaccurate food orders is denoted by $O_C$. The value is computed below:

$$\begin{gathered} O_C=33+54+31+13 \\ =131 \end{gathered}$$

Let the total number of orders be denoted by N.

The probability of getting an inaccurate food order is calculated as shown below:

$$\begin{gathered} P\left(E\right)=\frac{O_C}{N} \\ =\frac{131}{1118} \\ =0.117174 \end{gathered}$$

Therefore, the probability of getting a food order that is not accurate is equal to 0.117.
