You can put this solution on YOUR website!
Let x = number of orders received per day
X has a poisson distribution with parameter l = 6

i. No order will be received?
ii. No more than 2 orders will be received?
iii. At least 3 orders will be received?
Answers:
i) P(X=0)= 0.0025
ii) P(X<=2)= 0.062
iii) P(x >=3) = 1-P(X<=2) = 1-0.062 = 0.938
