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

125 blue vehicles

Step-by-step explanation:

In this question, we are going to estimate the number of vehicles of a specific color given that there are some numbers of both vehicle models present in a sample.

Now to solve this question, we are going to treat the sample numbers as a ratio.

The ratio here is thus 7 black to 5 blue I.e 7:5

We have 300 vehicles, we now want to estimate the number of blue vehicles present.

From the sample ratio, there are a total of 12 vehicles

Now the total number of blue vehicles would be 5/12 * 300 = 125

There are 125 blue vehicles
