Expert Answer

Step 1

From the given information,

45% of consumers comfortable having drones deliver their purchases.

That means probability of consumers comfortable having drones, P=45%=0.45

                                                                                                                                     Then, q=1-P

                                                                                                                                                    =1-0.45

                                                                                                                                                     =0.55

Step 2

 Number of consumers, n=6

And, exactly four of them a...
