An article reported that 7 in 10 auto accidents involve a single vehicle (the article recommended always reporting to the insurance company an accident involving multiple vehicles). Suppose 15 accidents ar randomly selected. Use Appendix Table A.1 or SALT to answer each of the following questions. (Round your answers to three decimal places.) USE SALT (a) What is the probability that at most 4 involve a single vehicle? 0.001 (b) What is the probability that exactly 4 involve a single vehicle? 0.001 (c) What is the probability that exactly 6 involve multiple vehicles? 0.012 X (d) What is the probability that between 2 and 4, inclusive, involve a single vehicle? (e) What is the probability that at least 2 involve a single vehicle? (f) What is the probability that exactly 4 involve a single vehicle and the other 11 involve multiple vehicles? 4
