Extracted text: Determine the probability P(1 or fewer) for a binomial experiment withn38 trials and the success probability p 0.3. Then find the mean, variance, and standard deviation. On Part 1 of 3 Determine the probability P(1 or fewer). Round the answer to at least four decimal places. P(1 or fewer) = Part 2 of 3 Find the mean. If necessary, round the answer to two decimal places. The mean is Part 3 of 3 Find the variance and standard deviation. If necessary, round the variance to two decimal places and standard deviation to at least three decimal places.
