independent event-the occurrence of one event does not affect the probability of the occurrence of another event
compound event-two or more events considered
dependent event-the occurrence of one event affects the probability of the occurrence of another event
The random variable is the number of cars held up at the intersection.
A random variable is one whose value is aleatory, then you can not know anticipatedly the outcome for sure. In this case, the number of cars held up at the intersection may be different at any time inside the range given and you cannot know the number of cars that there will be in a future moment.

Answer:
2,800 CUV cars were sold
Step-by-step explanation:
7 out of 10 are CUV
Total sold are 4,000
Set them equal to each other:
![\frac{7}{10} = \frac{x}{4000}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B10%7D%20%20%3D%20%5Cfrac%7Bx%7D%7B4000%7D)
Cross multiply:
![7 * 4,000 = 10*x](https://tex.z-dn.net/?f=7%20%2A%204%2C000%20%3D%2010%2Ax)
![28,000=10x](https://tex.z-dn.net/?f=28%2C000%3D10x)
Solve for x:
![\frac{10x}{10} =\frac{28,000}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B10x%7D%7B10%7D%20%3D%5Cfrac%7B28%2C000%7D%7B10%7D)
x = 2,800
