b) 0.4866
c) 0.8111
Step-by-step explanation:
The probability that the next call come within the next t minutes is:
According to this model,
a) the probability that a call in comes within 1/2 minutes is
=0.1535
b) the probability that a call in comes within 2 minutes is
=0.4866
c) the probability that a call in comes within 5 minutes is
=0.8111
3 1/2 divided by 2 1/4 = 1.55555556
1.55555556 Rounded is 1.55
Because if it is linear it is a straight line so the slope must always be equal to eachother
