Given that the number of arrivals of data packet in the receiver follows a Poisson distribution on which arrival rate is 10 arrivals per second. What is the probability that the number of arrivals is more than 8 but less than 11 during a time of interval of 2 seconds?

What will be an ideal response?


The number of arrivals during a time interval of 2 seconds follows a Poisson

distribution with mean 10 × 2 = 20 arrivals/sec. Hence,
