Step-by-step explanation:
Assuming the order in which he answers the questions matter the answer is the number of permutations of 8 in 10.
This is 10! / (10-8)!
= 1,814.400.

Answer:
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
