Question

Please Calculate the Comulative Probability and Random Digit Assignment. Please Solve the problem ASAP. Show me how it is done in Excel if possible:

A store has one counter. The probability of inter-arrival time (in min) and service time (in min.) of customers are given in the following table.

Distribution of time between Arrival

Interarrival time(min)	Probability	Cumulative Probability	Random Digit Assignment
1	0.13
2	0.15
3	0.03
4	0.17
5	0.06
6	0.14
7	0.15
8	0.09
9	0.19
10	0.08

Answer 1

	Interarrival time(min)	Probability	Cumulative Probability	Random Digit
	Assignment
	1	0.13	0.13	1------13
	2	0.15	0.28	14-----28
	3	0.03	0.31	29----31
	4	0.17	0.48	32----48
	5	0.06	0.54	49----54
	6	0.14	0.68	55---68
	7	0.15	0.83	69----83
	8	0.09	0.92	84---92
	9	0.02	0.94	93---94
	10	0.06	1	95---00
	sum=	1
Note:	sum of probabilty should be  1
	so I have changed last two probability
	please see the same and
	please alter accordingly
