victus00 [196]

Answer:

a) 0.19

b) 0.9689

c) ≈ 6 cars

Step-by-step explanation:

Rate at which cars arrive = 12 cars/hour = 1/5 cars/minute

time needed by each car to complete ATM transaction = 6 minutes = 1/6 car/minute

capacity of lane = 10 car

n = 10

<u>a) Calculate the probability of an arriving not using the ATM because the line is full</u>

p ( not using the ATM ) = 0.19

<u>b) probability that a car will not be able to use the ATM machine immediately on arrival</u>

P ( n > 0 ) = 1 - Po

                 = 1 - 0.0311 = 0.9689

<u>c) Average number of cars in the lane </u>

Lq = 5.74 ≈ 6 cars

attached below is the detailed solution
