If X represents the number of successes that occur in the n trials, then X is said to be a binomial random variable with parameters (n,p). Its probability mass function is given by (2.5)Pi≡P{X=i}=nipi(1-p)n-i,i
As its name suggests, the binomial distribution refers to random variables with two outcomes. Three examples of random variables with two outcomes are (1) smoking status — a person does or does not smoke, (2) exposure to benzene — a worker was or was not exposed to benzene in the work...

Alternatively, you can write X∼b(n,p), which means that your binomial random variable X follows a binomial probability distribution with n trials and an event probability of p. The previous examples assess probabilities corresponding with rolling sixes in a series of 10 die rolls. In this s...

Only two outcomes are possible (Success and Failure). Probability of success (p) for each trial is constant. A random variable Y= the number of successes. Thenegative binomialis similar to the binomial with two differences (specifically to numbers 1 and 5 in the list above): ...
