Formula :

Probability P( X - μ < 2σ) = 1 - ( 1 / K2 ) Where, K = Standard Deviation

Example:

Chebyshev's Inequality Theorem

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 %
