The probability distribution of the Poisson random variable X, representing the number of outcomes occurring in a given time interval or specified region denoted by t, is
where λ is the average number of outcomes per unit time
Given that
a. What is the probability that more than 100 cars pass her on any given Saturday?
The "R \\ ppois" function provides the left cumulative probabilities, as in Pr(X ≤ x).
b. Determine the probability that no cars pass.
The "R \\ dppois" s function provides the individual Poisson mass function probabilities Pr(X = x) for the Poisson distribution.
