Geophysicists determine the age of a zircon by counting the number of uranium fission tracks on a polished surface. a particular zircon is of such an age that the average number of tracks per square centimeter is 5.

a) what is the probability that a 2cm2 sample of this zircon will reveal at the most three tracks, thus leading to an underestimation of the age of the material?

b) how likely would it be to find a piece of zircon with an area greater than .5 cm2 between 2 tracks?
