A Geiger counter counts the number of alpha particles from radioactive material. Over a long period of time, an average of 25 particles per minute occurs. Assume the arrival of particles at the counter follows a Poisson distribution.

Find the probability that at least one particle arrives in a particular one second period. Round your answer to four decimals.

Find the probability that at least two particles arrive in a particular 2 second period. Round your answer to four decimals.
