Question 2
Suppose we want to model the number of action potentials in a given square centimeter of brain tissue in a particular region. If we assume that the probability of an action potential in all square centimeters of tissue in this region is the same and that the number of action potentials in any square centimeter of tissue in this region is independent of the number in any other similar area, we can model this situation using a:
◦
binomial random variable.
◦
geometric random variable.
◦
hypergeometric random variable.
◦
Poisson random variable.
