Get the probability of a matrices

I have a matrix E1

     1     1     4     5     1     1     3     1
     1     1     2     5     1     1     1     1
     3     4     1     3     5    10     5     4
     4     2     3     4     5     8     4     1
     1     2    12    16     1     1     3     3
     1     2    10    14     1     1     1     1
     1     1    10     8     2     5     3    15
     5     2     1     3     2    21     1    11

I sort the symbols into a table

     %calculate the freq%
[a,b]=hist(E1,unique(E1));
out=[b' sum((a),2)];

%Sorting into table%
Table = array2table(out,'VariableNames',{'Symbol','Count'})

%Rearrange table in descending order%
tblB = sortrows(Table,{'Count'},{'descend'})

And the result turns into this

 Symbol    Count
    ______    _____

     1        25   
     3         8   
     2         7   
     5         7   
     4         6   
    10         3   
     8         2   
    11         1   
    12         1   
    14         1   
    15         1   
    16         1   
    21         1   

So my question is how can I get the probabilities of each symbols in vector?

The desired result is as below

    mat=[0.3906 0.125 0.1094 0.1094 0.0938 0.0469 0.0313 0.0156 0.0156 0.0156 0.0156 0.0156 0.0156];

mat=tblB.Symbol./sum(tblB.Count)  %though the pattern is not discernible

Thank you.

After some corrections , I get the answer.

 mat=[];
 for matz=1:height(tblB)
mat=[mat,tblB.Count(matz)/sum(tblB.Count)]
end
