Question

. Suppose that the number of Bigfoot sightings per year in the Northwestern US is well-modeled by a Poisson random variable with an average of 3 sightings occurring per year. Calculate the probability that in a given year there are at least 4 sightings in this region, given that there are at least 2 sightings.

Step-by-step explanation:

Given that  the number of Bigfoot sightings per year in the Northwestern US (say X) is well-modeled by a Poisson random variable with an average of 3 sightings occurring per year. the probability that in a given year there are at least 4 sightings in this region, given that there are at least 2 sightings

=Prob that there are atleast 4 sightings/Prob atleast 2 sightings

(since intersection of these two events is atleast 4)

= Reqd prob = 0.1944
