You are given the table


\begin{array}{cc}x&f\\1&4\\2&6\\3&2\\4&6\\5&2\end{array}

Find
\sum \limits_(i=1)^5f_i=4+6+2+6+2=20.

Then you can get new probability table


\begin{array}{cc}x&p\\1&(4)/(20)=0.2\\ \\2&(6)/(20)=0.3\\ \\3&(2)/(20)=0.1\\ \\4&(6)/(20)=0.3\\ \\5&(2)/(20)=0.1\end{array},

where
p_i=(f_i)/(\sum \limits_(i=1)^5f_i).

The probability distribution bar graph you can see in attached diagram.
