answer is 20%
heres why
ok so if there is 60 balls all together out of all the color and you want to get a blue ball but the blue has less balls out of all the other colored balls so there is would be a less percent of getting a ball of that color out of 100%
you would need to take the blue color of balls and put in a fraction with the amount of balls together
so that would be 12/60
you half 12/60 and you would need to get the percent which is 20% so you have a 20% of getting a blue colored ball
