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 following table:

 

Low

Medium

High

On

.50

.10

.05

Off

.25

.07

.03

Consider the following events:

A: { On }


B: { MediumorOn }


C: {Off and Low}


D: {High}


a. Find P(A).


b. Find P(B).


c. Find P(C).


d. Find P(D).


e. Find P(Ac).


f. Find P(AB).


g. Find P(AB).


h. Consider each possible pair of events taken from the events A, B, C, and D. List the pairs of events that are mutually exclusive. Justify your choices.
