Assumptions underlying the binomial distribution
The binomial distribution is applicable to a wide range of applications where a random sample of categorical measurements is obtained.
Evaluating binomial probabilities
If we are satisfied that a binomial distribution is appropriate, it can be used to obtain the probability of any number of successes.
We recommend translating any interval into its form using 1/2 before finding its probability.
(This translation of intervals is particularly useful when using the normal approximations that are described in the following pages.)
