a. P(X=3), If mean=2.5
b. P(X<=1), If mean=2.0
c. P(X>=2), If mean=3.0

Question 1171635: compute the following poisson probabilities (to 4 decimal places) using the formula:
a. P(X=3), If mean=2.5
b. P(X<=1), If mean=2.0
c. P(X>=2), If mean=3.0

e^(-2.5)2.5^3/3!=0.2138
-
this would be x=0 and x=1
e^-2.5=0.0821
e^(-2.5)*2.5=0.2052
that sum is 0.2873
-
for x>=2, that is 1- p (x<=1) or 0.7127
