如何正确地理解和把握概率的意义，形成正确的随机观念是学习概率的一个重点，同时也是一个难点．同学们在学习概率的初期，难免对概率存在一些错误认识．建议大家在面对概率问题的时候，不妨多从频率的角度进行思考，多动手进行操作，通过活动和试验不断地体会概率的意义． How to correctly understand and grasp the meaning of probability and form the correct concept of randomness is a key point of learning probability, and it is also a difficult point. Students in the early stages of learning probability, it is inevitable that there is some wrong understanding of probability. It is suggested that when faced with the probability problem, we may think more frequently from the perspective of frequency, more hands-on operations, through the activities and experiments constantly understand the significance of the probability.
