WebNice problem! If n represents the number of trials and p represents the success probability on each trial, the mean and variance are np and np (1 - p), respectively. Therefore, we have np = 3 and np (1 - p) = 1.5. Dividing the second equation by the first equation yields 1 - … WebJun 24, 2024 · A bimodal distribution is a probability distribution with two modes. We often use the term “mode” in descriptive statistics to refer to the most commonly occurring value in a dataset, but in this case the term …
WebJul 24, 2016 · The binomial distribution model is an important probability model that is used when there are two possible outcomes (hence "binomial"). In a situation in which there were more than two distinct outcomes, a multinomial probability model might be appropriate, but here we focus on the situation in which the outcome is dichotomous. WebJan 4, 2024 · The mean and the variance of a random variable X with a binomial probability distribution can be difficult to calculate directly. Although it can be clear what needs to be done in using the definition of the expected value of X and X 2, the actual execution of these steps is a tricky juggling of algebra and summations.An alternate way to determine the …
