Answer:
Green: 50%
Purple: 25%
Black: 25%
Step-by-step explanation:
Well, the circle has 4 equal sections.
2 are green
1 is purple
1 is black
To find the probability of the spinner landing on each section we make a fraction.
Green)
2/4 simplified,
1/2, as a percent is 50%
Purple)
1/4,
1 divided by 4 = .25
To make that into a percent we move the decimal 2 places to the right -> 25%
Black)
1/4
1 divided by 4 = .25 as a percent 25%
Answer:
1 / 16
Step-by-step explanation:
Number of options = 4
Number of correct answers = 1
Number points gained for a correct answer = 1
Number of points lost for an incorrect answer = 1/4 = 0.25
Probability of choosing a correct option = 1/4
Probability of choosing an incorrect option = 3/4
x ____ 1 ______ - 1/4
P(x) __ 1/4 ______ 3/4
Expected gain or loss :
E(x) = Σx*p(x)
E(x) = (1 * 1/4) + (-1/4 * 3/4)
E(x) = 1/4 - 3/16
E(x) = (4 - 3) / 16
E(x) = 1 /16
A gain of 1/16
