Edgar records the time that it takes his school bus to take him from the bus stop to school each day. this is a ___________ random variable.


  1. Since it involves decimal values, this is a continuous random variable.

    What are continuous and discrete variables?

    • Continuous variables: Can assume decimal values.
    • Discrete variables: Assume only countable values, such as 0, 1, 2, 3, …
    In this problem, the time assumes decimal values, hence it is a continuous random variable.
