a The probability of success on a single trial. b The total number of trials. c The average number of successes. 4 What type of outcomes does the binomial distribution model? a Two possible outcomes (success or failure). b Multiple outcomes. c Continuous outcomes. 5 What is the mean of a binomial distribution? a μ = n + p b μ = n / p c μ = n * p 6 What is the variance of a binomial distribution? a σ² = n * p b σ² = p * (1-p) c σ² = n * p * (1-p) 7 Which of the following is a requirement for a binomial distribution?

a The average outcome. b The number of trials. c The probability of success. 35 In the Poisson distribution, what does a higher λ indicate? a More frequent events in the interval. b Fewer events in the interval. c A lower probability of success. 36 Which of the following is a key assumption for using Poisson as an approximation?
