![A small-business Web site contains 100 pages and 60%, 30%, and 10% of the pages contain low, moderate, and high
graphic content, respectively. A sample of four pages is selected without replacement, and X and Y denote the number
of pages with moderate and high graphics output in the sample, respectively. What is the variance of Y given that there
are no pages with moderate graphics drawn? Express your answer up to three decimal places.
