Answer 1

maybe

red_percent = 100 * red / (red + blue)
blue_percent = 100 * blue / (red + blue)

or:

red_percent = 100 * red / (red + blue)
blue_percent = 100 - red_percent

Answer 2

if you have the numbers of occurencies you can do that with just a little of math

red_ballons = 10
blue_ballons = 90

total_ballons = red_ballons + blue_ballons

red_percentage = red_ballons  / total_ballons  * 100 #*100 because %
blue_percentage = blue_ballons  / total_ballons  * 100 #*100 because %

Im not sure if this is what you were looking for but i hope it helps
