An experiment consists of tossing a single die and observing the number of dots that show on the upper face. Events A, B, and C are defined as follows. A: Observe a number less than 4. B: Observe a number less than or equal to 2. C: Observe a number greater than 3. Find the probabilities associated with the following events using either the simple event approach or the rules and definitions from this section. (Enter your probabilities as fractions.)
