Because these numbers are not symbolic objects, chebyshevt returns floatingpoint results. Chebyshev polynomials for numeric and symbolic arguments. In probability theory, chebyshevs inequality also called the bienaymechebyshev inequality guarantees that, for a wide class of probability distributions, no more than a certain fraction of values can be more than a certain distance from the mean. In probability theory, chebyshevs inequality guarantees that, for a wide class of probability. Depending on its arguments, chebyshevt returns floatingpoint or exact symbolic results.
