A company vehicle is available in black or blue. A random sample includes seven black vehicles and five blue vehicles. If there are 300 company vehicles, how many are blue

The answer is 125

Step-by-step explanation:

So, there are 12 vehicles.

5 are blue.

7 are black.

This makes 5/12 vehicles blue.

Multiply 5/12 by 300 vehicles and what do you get?

You get 125.

125 vehicles are blue.
