一、题型战术,屡见不鲜初中学习概率的计算时,有的老师会为学生总结各种各样的题型:题型一概率与实数握手.中考的概率题常常放在实数的概念或运算背景下,使概率的考查与实数握手,这样的中考概率题给人新颖、别致的感觉.题型二概率与代数式言欢.初中的代数式包括整式、分式、根式等,将概率的考查放在代数式的概念、分解、运算等背景下,使学生的解答起点相同、背景公平,从而保证试题的公平性.题型三概率与方程(或方程组)相约.初中的方程(或方程组)包括一元一次方程、分式方程、一元二
First, the type of tactics, common occurrence of junior high school learning probability calculation, some teachers will summarize a variety of questions for students: a probability and real handshake. Probability questions are often placed on the concept of real numbers or computing background Under the probability test and real handshake, so the probability of the senior high school entrance examination questions give a person a new, unique feeling. Question two Probability and algebraic Huan Huan. Junior high school algebra, including the whole, fractional, radical, etc., the probability test on algebraic The concept of probability, decomposition, computing and other background, so that students answer the same starting point, the background is fair, so as to ensure the fairness of the questions. Question three probability and equation (or system of equations.) Junior high school equations (or system of equations) An equation, fractional equation, a dollar two
