[ 1/1Inequality]
    Assignment:Find the solution set of inequality 100(0.78-p)/(100p(1-p))^0.5 <1.96 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        100 * ( 0.78 - p ) / ( 100 * p * ( 1 - p ) ) ^ 0.5 <1.96         (1)
        From the definition field of divisor
         100 * x * ( 1 - x ) ≠ 0        (2 )

---

    From inequality(1)：
         p ＞ 0.689295
    From inequality(2)：
         p < 0 或  0 < p < 1 或  p ＞ 1

---

    From inequalities (1) and (2)
         0.689295 < p < 1 或  p ＞ 1    (3)

---

    The final solution set is :
         0.689295 < p < 1 或  p ＞ 1
