Answer:
A confidence level is the probability or possible outcome of an object/event being observed falls within a specified range of values. One example is a survey made among 42% voters that they think the vice president will win as president on the next election with a 90% confidence level. 90% here means that if the survey is repeated again among higher number of population, 90% of the time most likely you will get the same result of 42%.
