Let æ be a random variable that possesses a binomial distribution with p = 0.9 and n = 15. Using the binomial formula or tables, calculate the following probabilities. Also calculate the mean and standard deviation of the distribution. Round solutions to four decimal places, if necessary. P(x > 11) : P(x < 2) %3D P(x = 14) = %3D
