<u>Step-by-step explanation:</u>
Here we have , Based on a survey, that 46% 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 three on them are comfortable with delivery by drones. We need to find the values of n,x,p,and q .Let's find out:
According to question , 46% of consumers are comfortable having drones deliver their purchases , So , Probability of success :
⇒
And , probability of failure :
⇒
⇒
Now , n = Number of people randomly selected = 5
x = Number of people exactly comfortable = 3
Therefore , .
