Use the data in the following table, which lists drive-thru order accuracy at popular fast food chains. Assume that orders are randomly selected from those included in the table. Order Accurate Order Not Accurate Drive-thru Restaurant C 250 34 A 326 38 B 265 56 D 130 14 If one order is selected, find the probability of getting an order from restaurant A or D or an order that is not accurate. The probability of getting an order from restaurant A or D or an order that is not accurate is (Round to three decimal places as needed.)
