Question

Example #2: 

A die is rolled. Assume that a random variable X represents the outcomes of this experiment. Construct a probability distribution table and represent this probability distribution graphically. (Use the x-axis for values of X and the y-axis for P(X)). 

Example #3: 

A coin is tossed 3 times. Suppose that the random variable X is defined as the number of heads. Construct a probability distribution of X and represent this probability distribution graphically. (Use the x-axis for values of X and the y-axis for P(X)). 

Answer 1

Example 2:

Outcome X (Number appear on die after rollling it)	1	2	3	4	5	6
Probability P(X)	1/6	1/6	1/6	1/6	1/6	1/6

Example 3:

Outcome	HHH	HHT	HTH	HTT	THH	THT	TTH	TTT
X (Number of Heads)	3	2	2	1	2	1	1	0

X	0	1	2	3
P(X)	1/8	3/8	3/8	1/8
