某林业部门统计某种幼树在一定条件下的移植成活率，结果如下表所示：
移植总数（n） | 200 | 500 | 800 | 2000 | 12000 |
成活数（m） | 187 | 446 | 730 | 1790 | 10836 |
成活的频率 (m/n)
| 0.935 | 0.892 | 0.913 | 0.895 | 0.903 |
【分析】
由题意根据概率是大量重复实验的情况下，频率的稳定值可以作为概率的估计值，即次数越多的频率越接近于概率进行分析即可．
【详解】解：概率是大量重复实验的情况下，频率的稳定值可以作为概率的估计值，即次数越多的频率越接近于概率，
∴这种幼树移植成活率的概率约为0.9.
故答案为：0.9.
