Question

Use the data in the following table, which lists drive-thru order accuracy at popular fast food chains. Assume t in the table that orders are randomly selected from those included Drive-thru Restaurant D 325 280 240 133 Order Accurate Order Not Accurate 36 52 38 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? The probability of getting two orders from Restaurant D is.The eventsindependent because choosing the first order second order (Round to four decimal places as needed.) V the choice of the are not are

Explanation / Answer

a)

number of orders from restaurant D are 133+14 =147

total orders are 325+36+280+52+240+38+133+14 =1118

so probability of getting an order from restaurant D = 147/1118

P(getting 2 orders from D with replacement) = (147/1118) * (147/1118)

                                                                               = 0.0173

The events are independent because choosing the first order doesnt depend on the choice of the second order
