Question:

The Physics at Home in Section 29.4 suggests tossing coins as a model of radioactive decay. An improved version is to toss a large number of dice instead of coins: each die that comes up a "one" represents a nucleus that has decayed. Suppose that N dice are tossed.
(a) What is the average number of dice you expect to decay on one toss?
(b) What is the average number of dice you expect to remain undecayed after three tosses?
(c) What is the average number of dice you expect to remain undecayed after four tosses?
(d) What is the half-life in numbers of tosses?
