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):
\[ P(X \leq k) = \sum_{i=0}^{k} \binom{n}{i} p^{i} (1 - p)^{n - i} \]How to Use the Binomial Probability Distribution Calculator
- Enter the number of trials (n).
- Enter the probability of success (p) (between 0 and 1).
