A. 0.2149
B. 0.6512
Step-by-step explanation:
Hello,
Please follow up properly with the steps in the attachment to get the right answer. Also use a good scientific calculator to arrive at the answer
We used a poisson distribution for This problem
λ = n p
n = 400
P = 1/100
λ = np = 400 x 1/100 = 4
P(X=x) = e^- λ. λ ^x/x!
= e^-4* 4^x/x!
A.
Probability of more than 5
1-p(0)+p(1)+p(2)+p(3)...p(5)
The answer is 0.2149
B.
Probability of between 3 cars and 6 cars
P(3)+p(4)...p(6)
= 0.6512
