Question 4. The probability that an individual will suffer from a bad reaction of a given serum is .003. Out of 10000 individuals, compute the following probabilities using both the Binomial and Poisson models.
Part 1. P (X = 0) where X is Binomial and then Poisson.
Part 2. P (X > 10) where X is Binomial and then Poisson.
CASE 1: When
is a Binomial Random
variable:
PARAMETERS:


Part 1.


Part 2.


The value of this probability can be found using the command "1 - BINOMDIST()" in MS-Excel as shown below.

This implies:

CASE 2: When
is a Poisson Random
variable:
PARAMETERS:


Therefore,



Part 1.


Part 2.


The value of this probability can be found using the command "1 - POISSON.DIST()" in MS-Excel as shown below.

This implies:
