在一次军事演习中，某舟桥连接到命令要赶到某小河D岸为进行中的A部队架设浮桥。假设舟桥连到达D岸的时间服从7点到7点30分这时间段内的均匀分布，架设需要20分钟时间，A部队到达D岸的时间服从7点30分到8点这时间段内的均匀分布。且舟桥连的到达时间和A部队的到达时间相互独立。求A部队到达D岸时能立即过桥的概率。

材料：
下面是一名高中老师的教育笔记。
大学刚毕业的我满怀激情，憧憬着成为一名优秀的教师，更期盼着成为一名优秀的班主任。可班级里的学生不像我想象中的那样勤奋、单纯，一些学生习惯以自我为中心、缺乏自制力、顽皮……问题多多，让我一时束手无策，犹如一盆盆冷水当头浇下，几乎浇灭了我追逐的教育梦想。
彷徨苦闷的我不禁扪心自问：“都是一样的人，凭什么我就教不好书，带不好班？”“不做教育科研，很难找到自己。”优秀班主任秦老师的这句话带领我走出了焦虑的泥潭。
从此，我成了名师们的一个“影子”：名师在哪儿，我跟到哪儿；专家在哪儿，我听到哪儿，每一个夜晚我都与书为伴。双休日，我是图书馆的常客，查课例、访实录、练语言、训表情。每周五的科研日，专家讲座、名师引领、尚创论坛，我都抢着去听去学，不知不觉“深陷”其中，浑然不知“今夕是何年”。
于是，我不仅提高了教学水平，而且懂得了该如何走进学生的心灵。我坚信每一个学生都是有巨大潜力的。对于学习困难的学生，我重在鼓励与帮扶；对于骄傲生，我重在鞭策与引导；对于过失生，我重在信任与关爱；对于屡错生，我重在耐心启发与理解……让每一个学生成长得更快。我在班上开展伙伴课堂，学生乐此不疲，“兵带兵”“兵学兵”“兵帮兵”，大家一同进步。我还建立了伙伴社团，让学生们互相取长补短。于是，我和学生、学生与学生之间的关系也融洽了。

Who am I?
Over time I have been changed quite a lot. I began as a calculating machine in France in 1642.
Although I was young I could simplify difficult sums.I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage. After I was programmed by an operator who used cards with holes,I could "think"logically and produce an answer quicker than any person. At that time, it was considered a technological revolution and the start of my "artificial intelligence". In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a"universal machine"to solve any difficult mathematical problem. From then on, I grew rapidly both in size and in brainpower. By the 1940s I had grown as large as a room, and I wondered if I would grow any larger. However, this reality also worried my designers. As time went by, I was made smaller. First as a PC(personal computer) and then as a laptop, I have been used in offices and homes since the 1970s.
These changes only became possible as my memory improved. First it was stored in tubes, then on transistors and later on very small chips. As a result, I totally changed my shape. As I have grown older I have also grown smaller. Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! And my memory became so large that even I couldn't believe it! But I was always so lonely standing there by myself, until in the early 1960s they gave me a family connected by a network. I was able to share my knowledge with others through the World Wide Web.
Since the 1970s many new applications have been found for me. I have become very important in communication, finance and trade. I have also been put into robots and used to make mobile phones as well as help with medical operations. I have even been put into space rockets and sent to explore the Moon and Mars. Anyhow, my goal is to provide humans with a life of high quality. I am now truly filled with happiness that I am a devoted friend and helper of the human race!
