A firm offers routine physical examinations as part of a health service program for its employees. The exams showed that 18% of the employees needed corrective shoes, 25% needed major dental work, and 3% needed both corrective shoes and major dental work. What is the probability that an employee selected at random will need either corrective shoes or major dental work?
