8 . 有机蔬菜是一类真正源于自然、富营养、高品质的环保型安全食品;绿色蔬菜是无机的.有机与无机主要标准是:有无使用化肥、农药、生长激素和转基因技术四个标准.有机蔬菜种植过程中不使用任何的人工合成的农药和化肥,但是绿色蔬菜在操作规程上是允许限量使用一些低毒,低残留的农药.种植有机蔬菜的土地一般来说都需要有三年或者三年以上的转换期,这就导致了种植有机蔬菜的时间成本高.某公司准备将M万元资金投入到该市蔬菜种植中,现有绿色蔬菜、有机蔬菜两个项目可供选择.若投资绿色蔬菜一年后可获得的利润
(万元)的概率分布列如下表所示:
且
的期望
;若投资有机蔬菜一年后可获得的利润
(万元)与种植成本有关,在生产的过程中,公司将根据种植成本情况决定是否在第二和第三季度进行产品的价格调整,两次调整相互独立且调整的概率分别为
(
)和
.若有机蔬菜产品价格一年内调整次数n(次)与
的关系如下表所示:
(1)求
的值;
(2)根据投资回报率的大小,现在公司需要决策:当
的在什么范围取值时,公司可以获得最大投资回报率.(投资回报率
