Success: A success refers to the desired outcome in an experiment or trial. For example, if we define "getting heads" as our success in flipping a coin, then landing on heads would be considered a success.
Bernoulli Trials: Bernoulli trials are independent experiments or trials with two possible outcomes - success or failure. Each trial has the same probability of success.
Probability Distribution: A probability distribution is a function that describes the likelihood of different outcomes occurring in an experiment or event. In the case of the binomial model, it provides probabilities for different numbers of successes in a fixed number of trials.
