Little’s Law Firm has two lawyers. Customers arrive randomly at an average rate of 1 per hour. Service times have a mean of 60 minutes and a standard deviation of 15 minutes. What is the average number of customers in Little’s Law Firm?

Answer 1

Answer:

$X=4$

Step-by-step explanation:

From the question we are told that:

Number of lawyers $N=2$

Arrival Rate $r= 1 per hour$

Mean $\=x=60min$

Standard deviation $\sigma= 15$

Generally, the equation for average number of customers in Little’s Law Firm

is mathematically given by

$X=Arrival rate (r) * Average service time (t)$

$X=1*\frac{60}{15}$

$X=4$
