B. You need to add 73 and 73
The probability of getting two red counters is 27.77%, the probability of getting two blue counters is 20.38%, and the probability of getting one of each color is 51.38%.
Given that Tina has two bags of counters, Bag A and Bag B, and there are 5 red counters and 3 blue counters in bag A, while there are 4 red counters and 5 blue counters in bag B, to determine, if Tina takes at random a counter from each bag, the probability of obtaining each counter, the following calculation must be made:
- Bag A red counter = 5/8 = 0.625
- Bag A blue counter = 1 - 0.625 = 0.375
- Bag B red counter = 4/9 = 0.444
- Bag B blue counter = 1 - 0.444 = 0.555
- Two red = 0.625 x 0.444 = 0.2777
- Two blue = 0.375 x 0.555 = 0.2083
- One red and one blue = 1 - 0.2777 - 0.2083 = 0.5138
Therefore, the probability of getting two red counters is 27.77%, the probability of getting two blue counters is 20.38%, and the probability of getting one of each color is 51.38%.

I don’t know if this is what your asking for but I think you just use the key to dot plot them.
18. just subtract 49.6 from 54. 54 - 49.6=4.4 He most lose 4.4 pounds.
19. all you need to do is add 4.6 to 83. 83+4.6=87.6 She will weigh 87.6 pounds
20. divide 910 by 7. 910÷7=130 The dog ate 130 grams per day
21. multiple 4.95 by 5. 4.95×5=24.75 Her total bill was 24.75
22. subtract 12.96 from 20. 20-12.96=7.04 Her change was 7.04
The correct answer for this question is this one:
<span>Gwen used elimination with multiplication to solve the system:
2x + 6y = 3
x − 3y = −5
Her work to find x is shown. Complete the explanation of her error. Then solve the system. If necessary, enter your answer as a reduced fraction.
2(x − 3y) = −5 --> 2(x-3y) = 2(-5)
2x − 6y = −5 --> 2x - 6y = -10
2x + 6y = 3 --> 2x + 6y = 3
2x − 6y = −5 --> 2x - 6y = -10
4x + 0y = −2 --> 4x = -7
x = −2/4 --> <u>x = -7/4</u>
x - 3y = -5
4(-7/4 - 3y = -5)
-7 - 12y = -20
-12y = -13
<u>y = 12/13</u>
Gwen forgot to multiply the right side by 2.
