Answer:

.2

Step-by-step explanation:

The probability has to sum to 1

Red + yellow + green + black + white = 1

.25+ .30 + .05 + black + white = 1

.6 + black + white =1

subtract  .6 from each side

.6-.6+ black + white = 1-.6

black + white = .4

They said black and white received the same number of votes, so they will have the same probability

2 black = .4

Divide by 2

2 black /2 =.4/2

black =.2

Calculate the annual return percentage
const2013 [10]
The annual returns will be calculated as follows:
a] Here we use the formula:
A=p(1+r/100)^n
A=future amount
p=principle
r=returns
n=time
We are given:
A=500, p=400, t=1
Plugging the values in the formula we obtain:
500=400(1+r)^1
simplifying and solving for r:
1.25=1+r
thus
r=1.25-1
r=0.25~25%

b] Using the formula above:
A=p(1+r/100)^n
A=2500+100=2600, p=2000, n=1 year
plugging the values in the equation we obtain:
2600=2000(1+r)^1
simplifying and solving for r we obtain:
2600/2000=1+r
1.3=1+r
hence
r=1.3-1
r=0.3~30%
