Question 1087191
Question:
A computer salesman average 1.5 sales per week. Use the poison distribution to find the probability that in a randomly selected week the number of computers sold is 1?".
 
Solution:
For a Poisson distribution, here λ = 1.5
and x=1.
Then 
pmf(x,λ)=λ^x(e^(-λ)/x!
=1.5^1(e^(-1.5))/1!
=0.33469
