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 315 262 241 133 Order Not Accurate 36 58 38 19 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 ▼ are are not disjoint because it ▼ is not is possible to ▼ pick an inaccurate order. receive an accurate order from Restaurant A. pick an order from Restaurant B, C, or D.

Answer 1

Solution: We are given the below tabular information:

	A	B	C	D	Total
Order Accurate	315	262	241	133	951
Order Not Accurate	36	58	38	19	151
Total	351	320	279	152	1102

If one order is​ selected, find the probability of getting an order from Restaurant A or an order that is accurate.

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

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

The events are not disjoint because it is possible to receive an accurate order from Restaurant A.
