解题方法
4 . 蓝莓种植技术获得突破性进展,喷洒A型营养药有--定的改良蓝莓植株基因的作用,能使蓝莓果的产量和营养价值获得较大提升.某基地每次喷洒A型营养药后,可以使植株中的80%获得基因改良,经过三次喷洒后没有改良基因的植株将会被淘汰,重新种植新的植株.
(1)经过三次喷洒后,从该基地的所有植株中随机检测一株,求-株植株能获得基因改良的概率;
(2)从该基地多个种植区域随机选取-一个,记为甲区域,在甲区域第一次喷洒A型营养药后,对全部N株植株检测发现有162株获得了基因改良,请求出甲区域种植总数N的最大可能值;
(3)该基地喷洒三次A型营养药后,对植株进行分组检测,以淘汰改良失败的植株,每组n株
,一株检测费为10元,n株混合后的检测费用为
元,若混合后检测出有未改良成功的,还需逐一检测,求n的估计值,使每株检测的平均费用最小,并求出最小值.(结果精确到0.1元)
(1)经过三次喷洒后,从该基地的所有植株中随机检测一株,求-株植株能获得基因改良的概率;
(2)从该基地多个种植区域随机选取-一个,记为甲区域,在甲区域第一次喷洒A型营养药后,对全部N株植株检测发现有162株获得了基因改良,请求出甲区域种植总数N的最大可能值;
