In order to study the germination rate of a batch of seeds, Qiang Qiang conducted two tests. In the first test, 75 out of 100 seeds germinated, and in the second test, all 25 seeds germinated. Then the germination rate of this batch of seeds was estimated.
为研究一批种子的发芽率，强强做了两次试验，第一次试验100粒种子有75粒发芽，第二次试验25粒种子全部发芽，则估算这批种子的发芽率为多少．
