Internet sites often vanish or move so that references to them cannot be followed. In fact, 13 % of Internet sites referenced in major scientific journals are lost within two years after publication. If a paper contains eight Internet references, what is the probability that all eight are still good two years later? Round your answer to three decimal places. What specific assumption must be made in order to calculate the probability? One does not need to make any assumptions; this is just a straightforward calculation. The paper containing the references must be obtained by random sampling. The occurrence of the site references in the paper are independent events. The occurrence of the site references in the paper are disjoint events, P (all eight are still good) =
