Suppose you approximating the solution of a simple differential equation involving the function , and you appeal to the relation

TRUE or FALSE? A  fixed-increment simulation clock is well-suited for simulations that model continuous-time systems such as the movement of an approaching weather system.

There are 5 random people in a room.  What is the probability that at least two of them share the same birthday?  (Assume 365 days are equally likely.)

Suppose that and are i.i.d. random variables. How would you simulate a discrete uniform random integer between 1 and 12 (e.g., a 12-sided die toss)?

Consider the discrete random variable such that
