UI A bag contains 4 red marbles, 6
white marbles, and 5 blue marbles.
If a marble is selected from the
bag, what is the probability that the
marble is not red?

the probability that the marble is NOT red is 1 - 4/15, or 11/15

Step-by-step explanation:

Find the probability that the marble IS red:  4/(4 + 6 + 5) = 4/15

Then  the probability that the marble is NOT red is 1 - 4/15, or 11/15

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
