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.

Restaurant A Restaurant B Restaurant C Restaurant D
Order Accurate 332 277 244 150
Order Not Accurate 31 51 30 10

If one order is selected, find the probability of getting an order from Restaurant A or an order that is accurate. Are the events of selecting an order from Restaurant A and selecting an accurate order disjoint events?
