Now you can apply the Binomial Theorem to binomial probabilities. To find the full probability distribution for a binomial experiment, expand the binomial

You can display the distribution of binomial probabilities as a graph.
Manufacturing Each hour at a cell phone factory, Quality Control (QC) tests the durability of four randomly selected phones. If more than one fails, QC rejects the entire production for that hour. If in one hour, 95% of the phones made are acceptable, what is the probability that QC rejects that hour's phone production?
What is a “success” in one trial of this binomial experiment?
Success in this experiment means that a phone fails the test.
Write the binomial expansion of
There is about a 1.4% chance that QC will reject the phones produced in the last hour.
