Understanding the Binomial Distribution

The binomial distribution models the number of successes in a fixed number of independent Bernoulli trials, each with the same probability of success.

Definition

The probability of getting exactly \( k \) successes in \( n \) trials is given by the binomial probability mass function (PMF):

\[ P(X = k) = \binom{n}{k} p^{k} (1 - p)^{n - k} \]

Where:

\( n \) = number of trials
\( k \) = number of successes
\( p \) = probability of success on a single trial
\( \binom{n}{k} \) = binomial coefficient

Cumulative Distribution Function (CDF)

The cumulative probability of up to \( k \) successes is calculated using the binomial cumulative distribution function (CDF):

\[ P(X \leq k) = \sum_{i=0}^{k} \binom{n}{i} p^{i} (1 - p)^{n - i} \]
