A long novel is opened to a random page; the probability that the page is numbered something between 21 and 31.
Harrizon [31]

Using the uniform distribution, considering that the novel has 435 pages, the probability that the page is numbered something between 21 and 31 is:

p = \frac{10}{435}

<h3>What is the uniform probability distribution?</h3>

It is a distribution with two bounds, a and b, in which each outcome is equally as likely.

The probability of finding a value between c and d is:

P(c \leq X \leq d) = \frac{d - c}{b - a}

Researching the problem on the internet, it is found that the novel has 435 pages, hence a = 0, b = 435, and the probability that the page is numbered something between 21 and 31 is given by:

P(21 \leq X \leq 31) = \frac{31 - 21}{435 - 0} = \frac{10}{435}

The perimeter of a rectangular garden is 860 ft. the two short sides of the garden are each 30 ft long. you are asked to find th
garik1379 [7]
<span>2(30)+2x=860 

This is because the 4 sides of the rectangle add up to the perimeter. 
The unknown side is x, and there are two of those, and there are also two sides of 30. 
They all add up to the perimeter. 

So: 
2(30) + 2x = 860</span>
