【简答题】
香港的“公屋制度”解决了30%以上，约200万人口的居住问题．内地对公租房建设也多有讨论，但尚未有一个城市真正大规模尝试．重庆市建设公共租赁住房，意在重点解决“夹心层”的住房问题，力争城市保障性住房的“全覆盖”．某班对学生以“公租房知识知多少”为主题进行了调查，该班的数学兴趣小组将本组的调查情况绘制下两幅不完整的统计图：（其中“A”表示“非常了解”，“B”表示“了解”，“C”表示“比较了解”，“D”表示“不了解”） （1）根据上图，计算出该组的总人数，并将该条形统计图补充完整； （2）若该班共有50人，试估计该班对公租房非常了解的人数； （3）该数学兴趣小组决定从本组“非常了解”的同学中任选两名代表本班参加学校的公租房知识抢答竞赛．若该组“非常了解”的同学中有1名女生，请用画树状图的方法，求出所选两名同学恰好是一男一女的概率．
