Online calculator which calculates the probability from the given standard deviation value (K), using Chebyshev Inequality Theorem / Rule.
Calculate probability, If the standard deviation is 12.
P(X - μ < 2σ) = 1 - ( 1 / 12 2 )
P(X - μ < 2σ) = 1 - ( 1 / 144 )
P(X - μ < 2σ) = 1 - 0.00694
P(X - μ < 2σ) = 0.99305
P(X - μ < 2σ) = 99.31 %
Therefore, probability is 99.31 %
