A Washington-based nonprofit research group recently released a report indicating that 60% of government workers acknowledge witnessing violations of ethical standards, policies, or laws in the past year, 40% of which went unreported. An additional 10% of government workers acknowledged making false reports of violations of ethical standards, policies or laws when they did not actually occur. What is the probability a randomly selected government worker did not witness violations of ethical standards, policies, or laws in the past year?
