Please give answer in detail dont just make the table also show the formula please
I Need this quesiton to solve with formula
.
A computer help desk receives new daily customer arrivals according to the following probability distribution:
# Arrivals 
Probability 
Random # 
0 
0.05 
0105 
1 
0.2 
0625 
2 
0.3 
2655 
3 
0.2 
5675 
4 
0.15 
7690 
5 
0.1 
9100 
The number of customers that the help desk has the capability to serve per day is based on the following probability distribution:
# Served 
Probability 
Random # 
3 
0.5 
0150 
4 
0.3 
5180 
5 
0.2 
8100 
If the number of arrivals exceeds the # served capability, the customers will receive top priority the next day. The random numbers drawn for a 5day simulation are as follows:
Arrival Random # 
Service random # 
19 
95 
34 
95 
39 
92 
90 
33 
97 
85 
What will the average number of delays be for the 5day simulation?
Solution
Just for convenience of presentation, following codes are employed in the simulation table below:
RN: Random number; NA: Number of customer arrivals; NC: Number of customers served;
NS: Number of customers served.

1 NS of Day 4 is served first and so of 5 new arrivals only 4 will be served. 
Thus, there is a delay of 2 customers over a 5day period or an average of 0.4 per day. ANSWER
Explanations:
Number of delays = NA + NS (of preceding day)  NC
No delay if NA < NC.
