Some atomic processes can result in the emission of an electron from the atom. Electrons emitted in this way can have discrete values of kinetic energy, which depend on the atomic energy levels. The probability that the electron has a particular value depends on interacions within the atom. Suppose a particular atomic process results in three values of the electron kinetic energy: Ψ1 has Ee = 10 eV, with probability 0.2. Ψ2 has Ee = 16 eV, with probability 0.3....

A Geiger counter beeps according to a Poisson process with rate of 1 beep per minute. (a). Let N_1 be the number of beeps in the first minute, N_2 the number of beeps in the second minute, N_3 the number of beeps in the third minute, etc. Let K be the smallest number for which N_K = 0, so minute # K is the first minute without a beep. Find E(K). (b). What is the probability that the time until...

An electron is one of the most fundamental particles in nature. It is everywhere, in all the matter we can see, and it is with electrons that light interacts when it is emitted, absorbed, or scattered in everyday matter. The electron has a more massive cousin called a muon, also with a charge of -1 e, but with a mass of 1.88x10-28 kg. The electron's mass is 9.11x10-31 kg. You can see why a muon is called a "heavy" electron....

(Poisson/Exponential/Gamma) Setup: The number of automobiles that arrive at a certain intersection per minute has a Poisson distribution with mean 4. Interest centers around the time that elapses before 8 automobiles appear at the intersection. Questions: (a) What is the probability that more than 3 minutes elapse before 8 cars arrive? (b) What is the probability that more than 1 minute elapses between arrivals?
