Question 255104: Can you help me solve this problem please?
At an outpatient mental health clinic, appointment cancellations occur at a mean rate of 1.5 per day on a typical Wednesday is Poisson.
A) What is the probability that no cancellations will occur on a particular Wednesday?
B) What is the probability that one cancellation will occur on a particular Wednesday?
C)What is that probability that more than two cancellations will occur on a particular Wednesday?
(I am having trouble with Poisson Distribution) Thank you very much.

----
If you have a TI-84 calculator you just plug in the mean rate and the
number of occurences you expect to get the probability.
A) What is the probability that no cancellations will occur on a particular Wednesday?
poissonpdf(1.5,0)= 0.2231..
---------------------------------
B) What is the probability that one cancellation will occur
on a particular Wednesday?
poissonpdf(1.5.1)= 0.3347
---------------------------------
C)What is that probability that more than two cancellations will occur on a particular Wednesday?
poissonpdf(1.5,2)= 0.2510
-------------------------------
If you need the formula I'll have to give it to
you later; have to run right now.
Cheers,
Stan H.
