The number of calls X that arrive at a hotel reception is mo

The number of calls (X) that arrive at a hotel reception is modeled as a poisson distribution with an average of 6 calls per hour (. What is the probability that there are exactly 5 calls in one hours? What is the probability that there exactly 4 calls in 2 hours?

Solution

X is Poisson with average 6 1 P(x=5) 0.1606 2 P(2x=4 when mean = 12) 0.0053 3 Exponential distribution 4 P(Y<20) 0.02657 5 P(Y in 30 /y=0in 10)
