Question from Poisson probability distribution

7. A sales form receives on the average of 3 calls per hour on its toll-free number. For any given hour, find the probability that it will receive a. At most 3 calls; b. At least 3 calls; and c. Five or more calls.

 

It's true that this is a question from Poisson's probability distribution. 

Are you looking for someone to do your excel homework? Our probability tutors provided the solution below to this question. If your parameters have changed, then you can still contact us for probability homework help. We can provide help with any excel assignment you might have. 

This follows a poisson Distribution     
Average  =  3  
Atmost 3 Calls   =  p(x<=3)
p(x<=3)   0.6472
b) At least 3 calls:  =  1-P(x<=2)
p(x>=3) = 0.57681
c. Probability of 5 or more calls   = 1-P(x<=4)
p(x>=5) = 0.1847
