Answer:

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

PLEASE help with these math questions

Questions 1, 2, 3, and 4 are exercises to give you practice with
common denominators. For each of these questions, change all
the fractions to common denominators, and the answers jump out at you.

#1). 5/12 = 25/60
   2/5 = 24/60
Make um negative, and then you'll have the answer right away.

#2). The one that's negative is obviously the least.
Both positive ones must be bigger than the negative one.
For the positive ones:

   2/5 = 6/15
   2/3 = 10/15 .
Now it's easy.

#3). This is tough. The least common denominator is 2,520 !
It's probably easier to just do the divisions and get the decimals
for each fraction.

   -5/8 = -0.625
   -7/9 = -0.777...
   -4/5 = -0.8
   -3/7 = -0.428...
Now it's easy to line um up.

#4). Sneaky one.
Look closely at each fraction.
B, C, and D are all less than 1, so they're not between 1 and anything more than 1.
8/5 is the only one that's more than 1.

#5). A fraction is just a short way to write a division problem.
When you see a fraction, it means

   "the top number divided by the bottom number" .

When you actually do the division, the quotient you get
is the decimal form of the fraction.

To change a decimal into a percent,
move the decimal point two places that way ==> .

The numbers in the boxes at the bottom of #5 are the correct numbers,
but they both should be negative. (because the -3/8 is negative)
