if 27 is the first number to be randomly generated, how many calls are made during the first ten - minute interval of the simulation?
(the table below is the probability distribution)

event	probability	cumulative probability	assigned numbers
1	0.15	0.20	06 - 20
2	0.25	0.45	21 - 45
3	0.30	0.75	46 - 75
4	0.20	0.95	76 - 95
5	0.05	1.00	96 - 100

Explanation:

Step1: Match number to event

Locate 27 in assigned numbers: 21-45 corresponds to Event 2.

Step2: Identify the number of calls

Event 2 represents 2 calls in the interval.

Answer:

2
