A probability distribution is just a range of expected values
from a situation or event that has outcomes involved.
Binomial, Poisson, and geometric distributions are normal
occurrences in nature and we can calculate the probability
of these events happening.
Expected value is a prediction of what may happen and
can help you to make intelligent decisions in life events of
finances, medical and relational events.

Why is it important and intriguing to know the probability of
an occurrence?
In what ways is a binomial distribution different that a
probability distribution and how can knowing how to find
the probability of these help is predict future events?
The special probability distributions of Poisson and
geometric help us make predictions of natural occurrences
such as hurricanes and earthquakes. Why is this important
for us to know and how can we use this knowledge to
protect and improve our world?
What is an expected value and how do I use this knowledge
to make informed decisions?
