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	326326	271271	247247	133133
Order Not Accurate	3333	5454	4040	1717

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?

Part 1

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

0.9010.901.

(Round to three decimal places as needed.)

Part 2

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

The events

are not

are

disjoint because it
