If one order is selected, find the probability of getting an order that is not accurate or is from Wendy’s. Are the events of selecting an order that is not accurate and selecting an order from Wendy’s disjoint events?

Use the data in the following table, which lists drive-thru order accuracy at popular fast food chains (data from a QSR Drive-Thru Study). Assume that orders are randomly selected from those included in the table.
