For this example I am getting 2e^(-2) and answer says 3e^(-2).

The number of power surges in an electric grid has a Possion distribution with mean of 1 power surge every 12 hours. What is the probability that there will be no more than 1 power surge in 24 â€“hour period?

Can anybody verify?

Thanks
