P.O.(Possible Outcome)

_____________________________
T.P.O. (Total Possible Outcome)

PROCEDURE (percent):
1- divide the possible outcome by the total possible outcome (it's just like dividing the numerator by the denominator in fraction)
2- multiply by 100

for example:
1/2
1 is the possible outcome
2 is the total possible outcome
1/2= 0.5
0.5x100 is equal to 50% percent
another way or a shortcut of getting the percentage is by moving the decimal 2 places to the right

1.)
P (red)
1/5= 0.2x100
Red / T.P.O. = 20%

2.)
P (green)
1/5= 0.2x100
Green / T.P.O. = 20%

3.)
P (blue or white)
2/5= 0.4x100
Blue & White / T.P.O. = 40%

4.)
P (not yellow)
4/5= 0.8x100
Not Yellow / T.P.O. = 80%

5.)
P (not red)
4/5= 0.8x100
Not Red / T.P.O. = 80%

6.)
P(blue or red or yellow)
3/5= 0.6x100
Blue, Red, Yellow / T.P.O.= 60%

MY QUESTION: What is the probability of getting white or yellow?

ANSWER: P 2/5= 0.4x100 White or Yellow/T.P.O. = 40%
- there is 40% chance of getting white or yellow if you spin once.
