Use the Poisson Distribution to find the indicated probability.
\n" ); document.write( "The number of calls received by a car towing service averages 19.2 per day (per 24-hour period). After finding the mean number of calls per hour, find the probability that in a randomly selected hour the number of calls is 2.
