Assignment: Chapter
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. Consider the events
below.
A: {High}
C: {Off andLow}
