Answer:
7/80
Step-by-step explanation:
(3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles
P ( green or yellow ) = number of green or yellow / total
= (3+4)/20 = 7/20
Replace
so we have (3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles
P (blue) = number of blue/ total
= 5/20 = 1/4
P ( green or yellow, replace, blue) = 7/20 * 1/4 = 7/80
Answer:
5
Step-by-step explanation:
Using the order operations, we go left to right, multiplying 3 by 2/3, giving us 2. Then we subtract 7 - 2 = 5.

Determine the area;
Area is calculated as thus:
![Area = \frac{1}{2}[(x_1.y_2 +x_2.y_3 + x_3.y_4 + x_4.y_1)-(x_2.y_1 +x_3.y_2 + x_4.y_3 + x_1.y_4)]](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5B%28x_1.y_2%20%2Bx_2.y_3%20%2B%20x_3.y_4%20%2B%20x_4.y_1%29-%28x_2.y_1%20%2Bx_3.y_2%20%2B%20x_4.y_3%20%2B%20x_1.y_4%29%5D)
Substitute values
![Area = \frac{1}{2}[(-5*4 +3*-6 + 6*-6 + -7*4)-(3*4 +6*4 + -7*-6 + -5*-6)]](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5B%28-5%2A4%20%2B3%2A-6%20%2B%206%2A-6%20%2B%20-7%2A4%29-%283%2A4%20%2B6%2A4%20%2B%20-7%2A-6%20%2B%20-5%2A-6%29%5D)
![Area = \frac{1}{2}[(-102)-(108)]](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5B%28-102%29-%28108%29%5D)
![Area = \frac{1}{2}[-102-108]](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5B-102-108%5D)
![Area = \frac{1}{2}[-210]](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5B-210%5D)
![Area = -105](https://tex.z-dn.net/?f=Area%20%3D%20-105)
![Area = 105](https://tex.z-dn.net/?f=Area%20%3D%20105)
