At a particular location on a river the number of fish caught per man-hour of fishing effort has a Poisson distribution with ?= 1.3 fish per man hour. Find the following probabilities:
a. That four fish will be caught by one man fishing 2 hours.
b. That six fish will be caught by three men fishing 20 minutes each.
Step by step method for computing probability based on Poison distribution is given in the solution.
