Question 4: According to historic data, on average, 5 traffic accidents occur per month at intersection A. If the probability that more than 2 accidents happen at that intersection is more than a given threshold p, the municipality will take corrective actions to improve the intersection safety. You have been asked to investigate if the municipality should take corrective actions or not. What type of probability distribution should you use to check this and is this a discrete or continuous probability distribution? (a) Normal, Continuous (c) Binomial, Discrete (b) Poisson, Discrete (d) Exponential, Continuous Question 5: Which of the following distributions does not have a symmetric form? (a) Z~N(0,1) (c) t-distribution (b) Uniform distribution (d) x² distribution
