The table below summarizes results from a study of people who refused to answer survey questions. A market researcher is not interested in refusals or subjects below 22 years of age or over 59. Find the probability that the selected person refused to answer or is below 22 or is older than 59.
The probability that a randomly selected person refused to answer the survey question or is below 22 or is older than 59 is _______ (Do not round until the final answer. Then round to three decimal places as needed.)
Refer to the table below. Given that 2 of the 245 subjects are randomly selected, complete parts (a) and (b).
a. Assume that the selections are made with replacement. What is the probability that the 2 selected subjects are both group O and type Rh*?
Homework Answers
= [ (total refused) + (ages below 22 & over 59 who responded) ] ÷ (total people)
= [ (183) + (79 + 208) ] ÷ 1273
