Question
Transcribed Image Text:**Table Data on Drive-thru Order Accuracy**
This section presents data on the drive-thru order accuracy at popular fast-food chains. Orders are assumed to be randomly selected from those included in the table.
**Drive-thru Restaurant Data:**
| | A | B | C | D |
|-------------------------|-----|-----|-----|-----|
| **Order Accurate** | 340 | 280 | 234 | 144 |
| **Order Not Accurate** | 36 | 53 | 38 | 19 |
**Analysis Task:**
Calculate the probability of an order being not accurate if one order is randomly selected.
**Solution:**
The total number of orders and the total number of orders that are not accurate need to be calculated to find the probability.
- Total orders not accurate: \(36 + 53 + 38 + 19 = 146\)
- Total orders: \( (340 + 36) + (280 + 53) + (234 + 38) + (144 + 19) = 1244\)
- Probability of an order not being accurate: \( \frac{146}{1244} \)
The probability of getting an order that is not accurate is \( \frac{146}{1244} \approx 0.1174 \).
Expert Solution
Step 1: Given data ;
| A | B | C | D | Toatl | |
| Order Accurate | 340 | 280 | 234 | 144 | 998 |
| Order Not Accurate | 36 | 53 | 38 | 19 | 146 |
| Total | 376 | 333 | 272 | 163 | 1144 |
