Answer with explanation:
We know that the formula for binomial probability :-
, where P(x) is the probability of getting success in x trials , n is the total number of trials and p is the probability of getting success in each trial.
Given : The probability that consumers are comfortable having drones deliver their purchases = 0.28
The total number of consumers selected = 5
To find the probability that when five consumers are randomly selected, exactly three of them are comfortable with delivery by drones , we substitute
n=5, x=3 , p=0.28 and q=1-0.28=0.72 in the above formula.

Thus, the probability that when five consumers are randomly selected, exactly three of them are comfortable with delivery by drones = 0.1138
