Suppose your call center usually gets 30 phone calls per hour. Compute the probability that a phone call will arrive within the next minute.

Solution

number of call in 1 hour = 30
number of call in 60 minutes = 30
number of call in 1 minutes = 30/60 =1/2=0.5
P(one phone call within next 1 minute ) = 0.5
