Use the Poisson Distribution to find indicated probability.

A naturalist leads whale watch trips every morning in March. Teh number of whales seen ha a Poisson distributyion with a mena of 2.2. Find the probability that on a randomly selected trip, the number of whales seen is 5.

Thank you for using the Jiskha Homework Help Forum. This i s not my area, but here are some sites on Poisson Distribution:

1. http://en.wikipedia.org/wiki/Poisson_distribution

2. (part II of #1): http://en.wikipedia.org/wiki/Poisson_process

3. http://mathworld.wolfram.com/PoissonDistribution.html

4. http://hyperphysics.phy-astr.gsu.edu/Hbase/math/poifcn.html

Jen:

If you went to the wikipedia site suggested by SraJMcGin, you would have the formula for calculating probabilities following a poisson distribution.

The Poisson distrbution is

f(k,a) =(a^k)*(e^-a)/k! where a is the expected observed in a time period, and k is the actual observed, and e is the exponential e. (Go to the wikipedia site; they can express formulas much better than here on Jiskha.)

In your example a=2.2, and k=5. Plug these into your formula. Hint: I get about 4.8%
