Answer:
Step-by-step explanation:
Given distribution is
x     0     1     2     3     4 Â
P(x) Â 0.25 Â 0.25 Â 0.25 Â 0.25 Â 0.25
Discrete Probability distribution consists of the values a random variable can assume and the respective probabilities of the values.
a) All probabilities must lies between 0 and 1
b) The sum of the probabilities must be equal to 1
Now the sum of the probabilities is given by
0.25+0.25+0.25+0.25+0.25=1.25
[tex]sum of the probabilities 1.25\neq 1[/tex]
