In questions like this one , you should first read the passage and then read the instructions. DO NOT read the alternatives. Then , with the information you got from the passage , try to awnser the question without looking at the alternatives. Now compare your awnser to the alternatives and eliminate the ones you are sure are wrong.
From the passage you learn that light pollution , caused by man-made lights , sometimes creates fogs and hazes that make the night sky look like a "dark sheet of paper".
If you compare what you understood from the passage to the alternatives , you ll realize that A) is the one that makes more sense and its more compatible with your awnser.
If you eliminated all alternatives you could but there still are 2 choices remaining and you are not sure which one it is , go back to the passage and try to find evidence for each alternative and try to eliminate one of the alternatives
AWNSER : A)
With a typical 52-card deck that has 4 jacks, Margaret is playing a game. The game is initiated by the first player to choose a jack. When choosing first, Margaret's probability of selecting Jack is 1/13.
The same will occur since probability will be determined using the formula necessary outcome divided by total outcome.
Here, the total number of cards in the deck (total outcome) equals 52.
Given that Margaret can select any of the four jacks, the necessary result (number of jacks) is 4.
Probability is 4/52, or 1 by 13, which is the required probability for the question.

<h3>What is a data frame?</h3>
A data frame refers to a two-dimensional array-like structure or table that is made up of rows and columns, which is typically used for storing data in R Studio using the R programming language.
In Computer programming, a data frame is a list of vectors that are all equal in length, and each column consist of values of one variable while each row consist of a set of values from each column.
<h3>The executable code in R Studio.</h3>
In this scenario, the code chunk that would be used to create a data frame that combines the two columns into a single column (phone_number) is:
- unite(customers, "phone_number", area_code, phone_num, sep="-"
