When you're evaluating P(n, k), you are essentially saying there are n objects and you will need to arrange them in k spaces.
This is essentially the same as:

, which follows the formula:

If you're dividing by 4!, you are evaluating P(6, 2)
Answer: 4051 girls, 4862 boys and 1570 adults over 50 years of age group attended the festival.
Step-by-step explanation:
Let x denotes the number of girls.
Then, the number of boys = x+811
The number of adults over 50 years of age = x-2481
Now, by considering the given scenario :-

Thus, the number of girls attended the festival = 4051,
Then number of boys = 4051+811=4862
Number of adults = 4051-2481=1570
Answer:
<h3> y = 2</h3>
Step-by-step explanation:

The slope-intercept form the equation of the line:
y = mx + b
Two lines are parallel if they hav the same slope.
no x in given line means m = 0 ⇒ y = b
The line goes through P so: 
2 = b
b = 2
so ithe equation of line parallel to given is:
y = 2
