Experiment. consists of . n. identical trials.. each trial results in one of two outcomes, a “success” or a “failure.”. T.Jagannadha. . Swamy. Dept of . ECE,Griet. Random Variable. A random variable . x. takes on a defined set of values with different probabilities.. For example, if you roll a die, the outcome is random (not fixed) and there are 6 possible outcomes, each of which occur with probability one-sixth. . Distribution. If the probability that James is late home from work on any. day is 0.4, what is the probability that he is late home. t. hree times in a five-day working week?. L . L. . L. . L. ’ L’. Binomial distributions. are models for some categorical variables, typically representing the . number of successes. in a series of . n. independent trials. .
