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.

Enter your answer in the provided box. Alpha particles produced by radioactive decay eventually pick up electrons from their surroundings to form helium atoms. Calculate the volume (in mL) of He collected at STP when 2.30 g of pure 226Ra is stored in a closed container for 136 years. (Assume that there are five alpha particles generated per 226Ra as it decays to 206Pb.)
