You can put this solution on YOUR website! Given Information:
4 red balls
8 blue balls
3 white balls
-------------------
With the given information, we know that there are 4+8+3 = 15 balls total.
The probability of chosing a white ball, denoted P(white), is found by dividing the number of white balls (3) over the total number of balls (15).
Be sure to reduce the fraction as much as possible.
To convert the fraction to decimal form, use long division or a calculator.
To convert a decimal to a percent, multiply the result by 100 (or move the decimal over 2 spots to the right).
P(white) = (number of white balls)/(number of balls total)
P(white) = 3/15
P(white) = 1/5
P(white) = 0.2
P(white) = 20%

Summary:
Answer as a fraction: 1/5
Answer as a decimal: 0.2
Answer as a percentage: 20%
