Geometric And Poisson Probability DistributionsSuppose we have an experiment in which we repeat binomial trials until we get our first success, and then we stop. Let be the number of the trial on which we get our first success. IN this context, is not a fixed number. This is a GEOMETRIC PROBABILITY DISTRIBUTION.

Geometric And Poisson Probability DistributionsEXAMPLE : Isabel Briggs Meyers developed personality type indicators. There are
16 personality types. One type that is “rare” is the INFJ ( introvert,
intuitive, feeling, judgmental) which occurs in 2.1% of the population.
Suppose a high school graduating class has 167 students, and a success
is the event that a student has the personality type INJF. a) Let be the number of successes ( INJF students ) in the
trials. If will the Poisson be a good approximation of the binomial ?
