Determine the probability P (1 or fewer) for a binomial experiment with n = 12 trials and success probability p = 0.3. Then find the mean, variance, and standard deviation. Part 1 of 3 Determine the probability P (1 or fewer). Round the answer to at least four decimal places. P (1 or fewer) = 0.0850 Part 2 of 3 Find the mean. Round the answer to two decimal places. The mean is 3.6 Part: 2 / 3 Part 3 of 3 Find the variance and standard deviation. Round the variance to at least two decimal places and standard deviation to at least three decimal places. The variance is X The standard deviation is
