Question

Based on a survey, assume that 41% 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.

Answer 1

Given the information on the problem, we have that it can be modeled as a binomial distribution. First, we are given the probability p which is p = 0.41. Then, since q = 1-p, then q = 1 - 0.41 = 0.59.

Since the experiment will involve 5 customers with 2 of them being a succesful event, we have that the total number of triales is n = 5 and the number of successes is x = 2
