Answer

Explanation:

Step1: Calculate total number of orders

Sum up all values in the table. $317 + 272+233 + 131+36+60+39+19=(317 + 36)+(272+60)+(233 + 39)+(131+19)=353+332+272+150 = 1107$

Step2: Calculate number of orders from Restaurant A

Sum up accurate and not - accurate orders from Restaurant A. $317+36 = 353$

Step3: Calculate number of orders not from Restaurant A

Subtract number of orders from Restaurant A from total number of orders. $1107 - 353=754$

Step4: Calculate the probability

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. $P=\frac{754}{1107}\approx0.681$

Answer:

$0.681$
