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
