Binomial Probabilities
Goal:
Use Binomial Probabilities to calculate probabilities.
DOD
In a binomial experiment there are
two
mutually exclusive outcomes, often referred to as
"success" and "failure."
If the probability of success is
, then the probability of failure is
± ²
.
Such an experiment whose outcome is random and can be either of two possibilities,
"success" or "failure", is called a Bernoulli trial, after Swiss mathematician Jacob Bernoulli
(1654 - 1705).
Examples of Bernoulli trials:
