Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. If convenient, use the appropriate probability table or technology to find the probabilities. The mean number of oil tankers at a port city is 14 per day. The port has facilities to handle up to 18 oil tankers a day. Find the probability that on a given day (a) fourteen tankers will arrive (b) at most three oil tankers will arrive (c) too many oil tankers will arrive
