Answer:
2 * 2 * 113
Step-by-step explanation:
452: 2 * 226
226: 2 * 113
113 is a prime number
452: 2 * 2 * 113
452: 2^2 * 113
The first book you select can be any one of 700.
. . . For each of those ...
The second book can be any one of the other 699.
. . . For each of those ...
The third book can be any one of the remining 698.
The total number of ways to gather three books from the shelves into your hands is (700 · 699 · 698) = <em>341,531,400 ways</em> .
<em>BUT ...</em>
When you bring three books to the check-out counter, Marian the Librarian doesn't know in which order you took them down off the shelves. You could have gathered the same three books in (3 · 2 · 1) = 6 different ways.
So, even though there are 341,531,400 ways to<em> </em>gather up three books, there are only (341,531,400 / 6) = 56,921,900 different GROUPS of three books that you can choose to take home.
Answer:
The answer is (2, ∞).
Step-by-step explanation:
The answer is (2, ∞) because both sides of the line will never meet and will forever increase on the .

Number of white cars = 110
The conditional probability that the person has the disease given that the test result is positive is of 0.4750 = 47.50%.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a previous event. The formula is:
In which:
- P(B|A) is the probability of event B happening, given that A happened.
- is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, the events are:
- Event B: Has the disease.
The percentages associated with a positive test is:
- 93.9% of 3.8%(has the disease).
- 4.1% of 100 - 3.8 = 96.2%(does not have the disease).
Hence:
The probability of both a positive test and having the disease is given by:
Hence the conditional probability is given by:
