Asked Nov 3, 2019

Based on a survey, assume that 26%of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the probability that when five consumers are randomly selected, exactly two of them are comfortable with delivery by drones. Identify the values of n, x, p, and q.

Step 1

From the given information,

26% of consumers comfortable having drones deliver their purchases.

That means probability of consumers comfortable having drones, P=26%=0.26

Then, q=1-P

=1-0.26

=0.74

Step 2

Number of consumers, n=5

And, exactly two of them are ...
