10) The overnight shipping business has skyrocketed in the last ten years. The single greatest predictor ofa 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. What is the probability that a respondent did not have a high level of satisfaction with the company? Round to the nearest hundredth. Satisfaction Levei Frequency of Use High Medium Low Total 5 per month 70 25 5 100 Total 460 220 20 700 11) Suppose a basketball player is an excellent free throw shooter and makes 91% of his free throws (i.e., he has a 91% chance of making a single free throw). Assume that free throw shots are independent of one another. Suppose this player gets to shoot three free throws. Find the probability that he misses all three consecutive free throws. Round to the nearest ten-thousandth. 12) A bag contains 10 white, 12 blue, 13 red, 7 yellow, and 8 green wooded balls. A ball is selected from the bag, its color noted, then replaced.

Round to the nearest tenthousandth. 13) Numbered disks are placed in a box and one disk is selected at random. If there are 6 red disks numbered 1 through 6, and 4 yellow disks numbered 7 through 10, nd the probability of selecting a yellow disk, given that the number selected is less than or equal to 3 or greater than or equal to 8
