Twenty-one subjects volunteer for a study of a new cold medicine. Twelve of the volunteers are ages 20-39, 6 are ages 40-59, and 3 are age 00 or older. If 5 volunteers are selected at random the following probabilities. (a) the probability that all the volunteers selected are ages 20-29 (b) the probability that 5 of the volunteers are ages 20-39 and 3 ore age 00 or older (c) the probability that 3 of the volunteers are ages 40-50 GEND (a) The probability that all the volunteers selected are ages 20-30 [ (Type an integer or a decimal rounded to five decimal places as needed) (b) The probability that 5 of the volunteers are ages 20-30 and 3 are age 60 or older is(Type an enteger or a decimal rounded to five decimal places as needed) (c) The probability that 3 of the volunteers are ages 40-50 is (Type an integer or a decimal rounded to five decimal places as needed.)
