Option b that is 1.33 is the right choice.
Step-by-step explanation:
Given:
Mean rate of arrival
= 8 planes/hr
Service time =
minute/plane
Mean service rate
=
=
planes/hr
Applying the concept Poisson-distributed arrival and service rates (exponential inter-arrival and service times)(M/M/1) process:
We have to find mean number of planes waiting to land that is mean number of customers in the queue .
Mean number of customers in queue
.
⇒
Considering,
,
is also mean number of customers in service.
⇒ 
⇒ Plugging the values.
⇒ 
⇒ 
⇒
So,
Mean number of planes in holding and waiting to land = 1.33
