an orange tree sapling is planted, it has a 30% chance of growing into a healthy and productive tree. If 18 ndomly selected saplings are planted, answer the following. Use technology or the binomial probability able to calculate the following probabilities. Round solutions to four decimal places, if necessary. ) What is the probability that exactly 6 of them grow into a healthy and productive tree? P(x = 6) = ) What is the probability that at least 6 of them grow into a healthy and productive tree? P(x ≥ 6) = What is the probability that at most 6 of them grow into a healthy and productive tree P(x ≤ 6) =
