A Bernoulli Trial is a random experiment with exactly two possible outcomes: success and failure. The probability of success remains constant in each trial.
Binomial Distribution: A discrete probability distribution that sums up the results of multiple Bernoulli Trials, specifying how many successes occur in a fixed number of trials.
Probability Mass Function (PMF): A function that gives the probability that a discrete random variable is exactly equal to some value.
Expected Value: The weighted average of all possible values that a random variable can take on, with weights being their respective probabilities.
