A Geiger–Muller tube is a type of gas‑filled radiation detector. It can detect particles like X‑rays, alpha particles, and beta rays (electrons). This is useful in quantizing the activity of a radioactive source or determining if an area containing radioactive material is safe to enter. Assuming that you have 1mol of gas, if a Geiger counter is filled with 9674 Pa of argon gas at room temperature (T=23.3 °C), what is the density, ρ, of the gas in this Geiger...

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...

On average, your professor typically calls on a student every 5 minutes throughout class time. He does not call on the same student twice in a class. Assuming that class is 75 minutes long and there are 32 students in the class, what is the probability that you will not be called upon during class? Does this situation qualify as a Bernoulli Trial? (2 points)
