Using probabilities as measure and as a dimension

I'd like to use probabilities as measure and as a dimension.
 
If we have a binary column gender, expressed a probability of being female, like the next one having four times 1.0, ten times 0.9 and one time 0.0:
 
  is_female
  ---------
        1.0
        1.0
        1.0
        1.0
        0.9
        0.9
        0.9
        0.9
        0.9
        0.9
        0.9
        0.9
        0.9
        0.9
        0.0
 
I'd like to have a bar chart with the rounded sum.
 
In this case it should show: 13 women and 2 men.
 
I'm using the next measure, which behaves as expected:
 
=round(Sum(is_female))+round(Sum(1-is_female))
 
Which dimension could I use?
 
If I use 'is_female' as dimension, it thinks that 0.9 is another categorical value.
 
If I use round(is_female), it counts the 0.9 occurrences as ten women.  Instead of 9 women + 1 man.
 
Thanks in advance
Cheers,

I solved it by detaching the info into two columns:  gender and gender_prob.
 
So, one original row can be detached into two new rows, one for female and the other one for male.
 

 

gender_prob     gender
-----------     ------
        1.0          F
        1.0          F
        1.0          F
        1.0          F
        0.9          F
        0.1          M
        0.9          F
        0.1          M
        0.9          F
        0.1          M
        0.9          F
        0.1          M
        0.9          F
        0.1          M
        0.9          F
        0.1          M
        0.9          F
        0.1          M
        0.9          F
        0.1          M
        0.9          F
        0.1          M
        0.9          F
        0.1          M
        0.0          M

 

 
Now, I can use gender as dimension and sum(gender_prob) as measure
