What you’ll learn5 learning objectivesChoose one objective for a focused lesson, or study the complete topic.6.1.1Poisson probabilities• use formulae to calculate probabilities for the distribution Po m^hSyllabus objective6.1.2The fact that if X Po+• use the fact that if X Po+ m^h then the mean and variance of X are each equal to m Proofs are not required.Syllabus objective6.1.3Poisson distribution• understand the relevance of the Poisson distribution to the distribution of random events, and use the Poisson distribution as a modelSyllabus objective6.1.4Binomial distribution• use the Poisson distribution as an approximation to the binomial distribution where appropriate The conditions that n is large and p is small should be known; n > 50 and np < 5, approximately.Syllabus objective6.1.5Normal distribution• use the normal distribution, with continuity correction, as an approximation to the Poisson distribution where appropriate. The condition that m is large should be known; 152m, approximately.Syllabus objective
