Suppose that the probability is 0.3 that any given citrus tree will show measurable damage when the temperature falls to 30°F. (a) If the temperature does drop to 30°F, what is the expected number of citrus trees showing damage in orchards of 1600 trees? (b) What is the standard deviation of the number of trees that show damage? (Round the answer to four decimal places.)
