[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0.2 <1-((1-0.6*b)-[(1-0.6*b)^2-4*(2*0.2*(1-0.2)-b*(1-b))*(0.36*b^2-1.2*b+1)])/(2*(0.36*b^2-1.2*b+1)) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        0.2 <1 - ( ( 1 - 0.6 * b ) - ( ( 1 - 0.6 * b ) ^ 2 - 4 * ( 2 * 0.2 * ( 1 - 0.2 ) - b * ( 1 - b ) ) * ( 0.36 * b ^ 2 - 1.2 * b + 1 ) ) ) / ( 2 * ( 0.36 * b ^ 2 - 1.2 * b + 1 ) )         (1)
        From the definition field of divisor
         2 * ( 0.36 * x ^ 2 - 1.2 * x + 1 ) ≠ 0        (2 )

---

    From inequality(1)：
         -0.084909 < b < 0.807905 或  1.666668 < b < 1.943671
    From inequality(2)：
         b < 5/3 或  b ＞ 5/3

---

    From inequalities (1) and (2)
         -0.084909 < b < 0.807905 或 或  1.666668 < b < 1.943671     (3)

---

    The final solution set is :
         -0.084909 < b < 0.807905 或 或  1.666668 < b < 1.943671
