Section 5.2 – Binomial Distributions
You should be able to do each of the following:
Name the features of a Binomial experiment
For a given binomial experiment,

b) Describe in words the success attribute
c) List all possible values of the random variable
Compute binomial probabilities for exactly x successes with the binompdf(n,p,x) feature
of the calculator.
o(Note: The binompdf(n,p,x) should be used in the home screen of the calculator)
Construct a probability distribution in the EDITOR of your calculator by using the
binompdf(n,p)
Compute probabilities for
