WebThis means that for every true-false statistics question Joe answers, his probability of success (p = 0.6) and his probability of failure (q = 0.4) remain the same. The outcomes of a binomial experiment fit a binomial probability distribution. The random variable X = the number of successes obtained in the n independent trials. WebThe Binomial Regression model can be used for predicting the odds of seeing an event, given a vector of regression variables. For e.g. one could use the Binomial Regression model to predict the odds of its starting to rain in the next 2 hours, given the current temperature, humidity, barometric pressure, time of year, geo-location, altitude etc.

If X ~ B(n, p) and Y ~ B(m, p) are independent binomial variables with the same probability p, then X + Y is again a binomial variable; its distribution is Z=X+Y ~ B(n+m, p): A Binomial distributed random variable X ~ B(n, p) can be considered as the sum of n Bernoulli distributed random variables.
