Step 1 :First, we need to calculate the total number of orders, the number of orders from Restaurant A, the number of accurate orders, and the number of accurate orders from Restaurant A.
Step 2 :The total number of orders is \(360 + 318 + 264 + 141 = 1083\).
Step 3 :The number of orders from Restaurant A is \(360\).
Step 4 :The number of accurate orders is \(328 + 268 + 233 + 130 = 959\).
Step 5 :The number of accurate orders from Restaurant A is \(328\).
Step 6 :Next, we calculate the probability of getting an order from Restaurant A, the probability of getting an accurate order, and the probability of getting an accurate order from Restaurant A.
Step 7 :The probability of getting an order from Restaurant A is \(\frac{360}{1083} = 0.332\).
Step 8 :The probability of getting an accurate order is \(\frac{959}{1083} = 0.886\).
Step 9 :The probability of getting an accurate order from Restaurant A is \(\frac{328}{1083} = 0.303\).
Step 10 :Finally, we calculate the probability of getting an order from Restaurant A or an order that is accurate.
Step 11 :This can be calculated by adding the probability of getting an order from Restaurant A and the probability of getting an accurate order, and then subtracting the probability of getting an accurate order from Restaurant A (since we are counting it twice).
Step 12 :The probability of getting an order from Restaurant A or an order that is accurate is \(0.332 + 0.886 - 0.303 = 0.915\).
Step 13 :Final Answer: The probability of getting an order from Restaurant A or an order that is accurate is \(\boxed{0.915}\).
