【学习要求】1.理解n次独立重复试验的模型.2.理解二项分布.3.能利用独立重复试验的模型及二项分布解决一些简单的实际问题.【学法指导】独立重复试验是研究随机现象的重要途径,二项分布是来自于独立重复试验的一个概率模型,学习中要把握它们的联系,掌握二项分布的特点.引入:分析下面的实验,它们有什么共同特点?(1)某人射击1次,击中目标的概率是0.8,他连续射击3次.
[Learning requirements] 1. Understand n independent repeated trial model 2. Understand the binomial distribution 3. Can use independent repeated trials model and binomial distribution to solve some simple practical problems. Is an important way to study the random phenomenon, binomial distribution comes from a probabilistic model of independent repeated experiments, learning to grasp their connection, to grasp the characteristics of binomial distribution.Read: Analyze the following experiments, what are their common characteristics? (1) A person shooting 1 times, the probability of hitting the target is 0.8, he shot 3 times in a row.
