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
