    Assignment:Find the solution set of inequality C(x,1)0.2^1*0.8^(x-1) <0.006 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         C( x , 1 ) * 0.2 ^ 1 * 0.8 ^ ( x - 1 ) <0.006         (1)

---

    From inequality(1)：
         x < 0.02413 或  x ＞ 32.285596

---

    The final solution set is :
         x < 0.02413 或  x ＞ 32.285596
