An experimental particle physicist captures six subatomic particles in a particle accelerator. In this experiment, the particles captured are either electrons or neutrons.It is not known how many among the subatomic particles are electrons or neutrons. However, using the results of diligent graduate students, it was determined that there is a 10% chance that any one of the 6 particles is an electron.
A. Compute the probability that 4 out of 6 particles are electrons.
B. Compute a numerical value for the average number of electrons.
C. Compute the standard deviation of the number of electrons.
D. Compute a numerical value for the average number of neutrons.
