Hi,

The mean number of homes sold by the company per day is 2

Poisson Distribution:  λ = 2  
Using TI Calculator: 

a. What is the probability that the company sells exactly 3 homes tomorrow?
   P(3) = poissonpdf(λ,x) = poissonpdf(2,3) = .1804

b. Find the probability of selling more than 2 homes on a particular day?
      1 - P(x ≤ 2 ) = 1 - poissoncdf(2,2)=  1 - .6767 =  .3233

Personally - use a Casio fx-115 ES plus 
Important You are comfortable using Your calculator

Wish You the Best in your Studies.
