K Twenty-four subjects volunteer for a study of a new cold medicine. Eleven of the volunteers are ages 20-39, 7 are ages 40-59, and 6 are age 60 or older. If 7 volunteers are selected at random, find the following probabilities. (a) the probability that all the volunteers selected are ages 20-39 (b) the probability that 5 of the volunteers are ages 20-39 and 2 are age 60 or older (c) the probability that 2 of the volunteers are ages 40-59 (a) The probability that all the volunteers selected are ages 20-39 is (Type an integer or a decimal rounded to five decimal places as needed.)
