You are given the table
[tex]\begin{array}{cc}x&f\\1&4\\2&6\\3&2\\4&6\\5&2\end{array}[/tex]
Find [tex]\sum \limits_{i=1}^5f_i=4+6+2+6+2=20.[/tex]
Then you can get new probability table
[tex]\begin{array}{cc}x&p\\1&\dfrac{4}{20}=0.2\\ \\2&\dfrac{6}{20}=0.3\\ \\3&\dfrac{2}{20}=0.1\\ \\4&\dfrac{6}{20}=0.3\\ \\5&\dfrac{2}{20}=0.1\end{array}[/tex],
where [tex]p_i=\dfrac{f_i}{\sum \limits_{i=1}^5f_i}[/tex].
The probability distribution bar graph you can see in attached diagram.
