Assume the number of episodes per year of otitis media, a common disease of the middle ear in early childhood, follows a Poisson distribution with parameter $\lambda=1.6$ episodes per year. Find the probability of not getting any episodes of otitis media in the first year of life.
Added by Michael V.
Step 1
We can do this by dividing the probability of not getting any episodes of otitis media by the probability of getting at least one episode of otitis media: $\frac{1}{1.6}=0.36$ Show more…

Assume that the number of episodes per year of otitis media, a common disease of the middle ear in early childhood follows a Poisson distribution with 2.7 episodes per year. What is the probability of having at most 2 episodes in the first year of life? (Approximate your answer to 4 decimal places). NB: You must follow instructions on how to approximate the answer, or your work will be marked as incorrect.

In a certain population an average of 12 new cases of esophageal cancer are diagnosed each year. If the annual incidence of esophageal cancer follows a Poisson distribution, find the probability that in a given year the number of newly diagnosed cases of esophageal cancer will be at least 2. Answer correct to 4 decimal places.
