A 100 percent chance of accuracy is impossible as there is always the potential for errors or inaccuracies in surveys. An 80 percent chance of accuracy is too low and would not be considered a reliable survey. A 50 percent chance of accuracy is equivalent to flipping a coin and guessing, which is not a useful survey. A 90 percent chance of accuracy is close but still allows for a larger margin of error.
