There are 4 white marbles, 6 red marbles, and 2 blue marbles. Once a marble is selected, it is not
replaced. Find the probability of selecting 2 blue
marbles.

For first question, there is 12 marbles at first. So the probability of choosing blue marble is 3/12=1/4. Then marbles are not replaced, the total number is 11. The probability of choosing red is 5/11. So the finally answer is (1/4)*(5/11)=5/44. The same method for second question. Need to notice that you have already choose 1 white marble, so the number of white marble also changed. The answer is (4/12)*(3/11)=1/11.

Step-by-step explanation:

1/6

Step-by-step explanation:

1. 4+6+2=12

2. 12 becomes the demoninator

3. 2 blue marbles over 12 marbles

4. 2/12

5. smiplify

6. 1/6

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
