Question

Find the indicated probability. Give your answer as a simplified fraction. 3) 3) The overnight shipping business has skyrocketed in the last ten years. The single greatest predictor of a company's success has been proven time and again to be customer service. A study was conducted to study the customer satisfaction levels for one overnight shipping business. In addition to the customer's satisfaction level, the customers were asked how often they used overnight shipping. The results are shown below in the following table. A customer is chosen at random. Given that the customer uses the company more than five times per month, what is the probability that they expressed low satisfaction with the company? Satisfaction level 140 25 Frequency of Use High Medium Low TOTAL 5 per month 70 TOTAL 460 10 400 5 200 100 20 C) 140 D) 140 A) B) 20

Explanation / Answer

P(low satisfaction | customer uses more than 5 times per month) = P(low satisfaction and customer uses more than 5 times per month) / P(customer uses more than 5 times per month)

= (5/700) / (100/700)

= 5/100

= 1/20

Option-B) 1/20
