4. geologists estimate the time since the most recent cooling of a mineral by counting the number of uranium fission tracks on the surface of the mineral. a certain mineral specimen is of such an age that there should be an average of 6 tracks per cm2 of surface area. assume the number of tracks in an area follows a poisson distribution. let x represent the number of tracks counted in 1 cm2 of surface area.
a)find p(x = 7).
b)find p(x ≥ 3).
c)find p(2 < x < 7).
d)find μx.
e)find σx
