Probability using binomial distribution
Webb3 feb. 2014 · The probability mass function for the binomial distribution is given by the formula: P ( X = r) = ( n r) p r ( 1 − p) n − r where the probability of a success is p (that is rolling a 6, and the probability of not rolling a 6; since there are the only two possibilities hence a binomial event) and the probability of a failure is therefore ( 1 − p). WebbThe binomial distribution with probability of success p is nearly normal when the sample size n is sufficiently large that np and n (1 − p) are both at least 10. The approximate normal distribution has parameters corresponding to the mean and standard deviation of the binomial distribution: µ = np and σ = np (1 − p)
