Question

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.

	Drive-thru Restaurant
	A	B	C	D
Order Accurate	314314	278278	242242	124124
Order Not Accurate	3131	5959	3737	1010

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?

The probability of getting an order from Restaurant A or an order that is accurate is

nothing.

(Round to three decimal places as needed.)

Are the events of selecting an order from Restaurant A and selecting an accurate order disjoint events?

The events
