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 D
A
C
127
Order Accurate
Order Not Accurate
310
276
238
30
58
38
11
If two orders are selected, find the probability that they are both from Restaurant D.
a. Assume that the selections are made with replacement. Are the events independent?
b. Assume that the selections are made without replacement. Are the events independent?

a. Assume that the selections are made with replacement. Are the events independent?
are
independent because choosing the first order does not affect the probability
The probability of getting two orders from Restaurant D is 0.0206. The events
of the choice of the second order.
(Do not round until the final answer. Round to four decimal places as needed.)
b. Assume that the selections are made without replacement. Are the events independent?
