A binomial experiment for the random variable X was performed with 10 trials. The probability of success was found to be 0.27. Determine the following probabilities: [Round to four decimal places.] a.) P(X=4)= b.) P(X 6) = The weight of apples harvested from a certain orchard are normally distributed with a mean of 81 grams and a standard deviation of 6.2 grams. What weight (to the nearest tenth) will separate the bottom 15% of apples from the rest? Your answer should be a decimal value rounded to the nearest tenth. The weight that separates the bottom 15% from the rest is grams
