The Poisson probability distribution is used when computing the probability of a certain number of successes
within a specified interval.
An experiment follows the Poisson process if it:
At a theme park, there is a roller coaster that sends an average of three cars through its circuit every minute between 6pm and 7pm. A random variable, X, represents the number of roller coaster cars to pass through the circuit between 6pm and 6:10pm.
Is this a Poisson random variable?
What is the probability that 35 cars will pass through the circuit between 6pm and 6:10pm?
