Here we use Chebyshev’s inequality and work backward. We want 50% = 0.50 = 1/2 = 1 – 1/ K2. The goal is to use algebra to solve for K . We see that 1/2 = 1/ K2. Cross multiply and see that 2 = K2. We take the square root of both sides, and since K is a number of standard deviations, we ignore the negative solution to the equation. hillary released cabinet
