a. Write the event that the outcome is "On" and "High" as an intersection of two events.
b. Write the event that the outcome is "Low" or "Medium" as the complement of an event.
Exercise 3.33
The outcomes of two variables are (Low, Medium, High) and (On, Off), respectively. An experiment is conducted in which the outcomes of each of the two variables are observed. The probabilities associated with each of the six possible outcome pairs are given in the accompanying two-way table.

For Information: Refer to Exercise 3.33. Use the same event definitions to do the following exercises.
Consider the following events:
A: {On}
B: {Medium or On}
C: {Off and Low}
D: {High}
