Q. A telemarketer with B2B Communications has a 20 percent historical probability of making a sale during a shift where 100 calls were made. Assign a random variable x, where the value of x is equal to the number of sales made during the shift. Describe the probability distribution of x and calculate the probability of the employee making exactly 28 sales during a 100-call shift. Illustrate what is the probability which the employee will make less than 28 sales during the 100-call shift? Illustrate what is the probability which the employee will make 28 or more sales during the 100-call shift?
