What is it?

This distribution with parameters n (number of trials, each one has only two outcomes: success or failure) and p (probability that event happened) is the discrete probability distribution.

Key characteristics:

• Number of trials is finite.
• The trials sre independent.
• Probability of success is constant for each trial.
• Each trial can result only in success or failure.

Examples:

The most clear example is tossing a coin.
