**Drive-Thru Order Accuracy Analysis**

To understand drive-thru order accuracy at popular fast-food chains, we refer to the data provided in the following table. This table shows the number of accurate and inaccurate orders for four different fast-food drive-thru restaurants, labeled A, B, C, and D. Assume that the orders are selected randomly from this dataset.

| **Drive-thru Restaurant** | **A** | **B** | **C** | **D** |
|---------------------------|-------|-------|-------|-------|
| **Order Accurate**        | 332   | 260   | 244   | 122   |
| **Order Not Accurate**    | 35    | 53    | 33    | 19    |

**Problem:**
If one order is selected at random, determine the probability that the selected order is not accurate.

**Solution:**
To calculate the probability of selecting an order that is not accurate, we follow these steps:

1. **Calculate the Total Orders:**
   - Total orders for Restaurant A = 332 (Accurate) + 35 (Not Accurate) = 367
   - Total orders for Restaurant B = 260 (Accurate) + 53 (Not Accurate) = 313
   - Total orders for Restaurant C = 244 (Accurate) + 33 (Not Accurate) = 277
   - Total orders for Restaurant D = 122 (Accurate) + 19 (Not Accurate) = 141

2. **Calculate the Total Number of Orders:**
   - Sum of all orders = 367 (A) + 313 (B) + 277 (C) + 141 (D) = 1098

3. **Calculate the Total Number of Not Accurate Orders:**
   - Total not accurate orders = 35 (A) + 53 (B) + 33 (C) + 19 (D) = 140

4. **Determine the Probability:**
   - Probability of an order being not accurate = Total Not Accurate Orders / Total Orders
   - Probability = 140 / 1098 ≈ 0.127

Therefore, the probability of getting an order that is not accurate is approximately **0.127** (rounded to three decimal places).
