Question: Given P(X) = 0.5, P(Y) = 0.4, and P(Y|X) = 0.3, what are P(X and Y) and P(X or Y)? (3 points)
A. P(X and Y) = 0.9, P(X or Y) = 0.75
B. P(X and Y) = 0.9, P(X or Y) = 0.1
C. P(X and Y) = 0.75, P(X or Y) = 0.15
D. P(X and Y) = 0.15, P(X or Y) = 0.1
E. P(X and Y) = 0.15, P(X or Y) = 0.75
Answer:
[tex]P(x\ and\ y) = 0.15[/tex]
[tex]P(x\ or\ y) = 0.75[/tex]
Explanation:
Given
[tex]P(x) = 0.5[/tex]
[tex]P(y) = 0.4[/tex]
[tex]P(y|x) = 0.3[/tex]
Solving (a): [tex]P(x\ and\ y)[/tex]
In probability, this is calculated as:
[tex]P(x\ and\ y) = P(x) * P(y|x)[/tex]
This gives:
[tex]P(x\ and\ y) = 0.5 * 0.3[/tex]
[tex]P(x\ and\ y) = 0.15[/tex]
Solving (b): [tex]P(x\ or\ y)[/tex]
In probability, this is calculated as:
[tex]P(x\ or\ y) = P(x) + P(y) - P(x\ and\ y)[/tex]
This gives:
[tex]P(x\ or\ y) = 0.5 + 0.4 - 0.15[/tex]
[tex]P(x\ or\ y) = 0.75[/tex]

How have ICE’s immigration policies affected our tax base and economy?
Answer:
The immigration policies have had both positive and negative effects on our economy. The U.S. tax base has increased in order to allot more money towards border enforcements and to allow for legal immigrants to live in the country, however the U.S. avoidance of immigration reform has also led to lower wages, lower tax revenue and lower productivity which deepens a vicious cycle aimed at prospective immigrants. The U.S. economy goes further in debt to serve the needs of Non-American Aliens, however the introduction of legal aliens in the country allows for debt forgiveness for America, as they have more workers.

Bread is the most popular baked foodstuff, although many other items may be baked. Heat is gradually transported from the surface to the core of cakes, cookies, and slices of bread.
A chocolate brownie, often known as a brownie, is a baked chocolate treat. Brownies come in a range of shapes and sizes, and their density determines whether they are fudgey or cakey. Brownies' upper crusts frequently, but not always, feature a shiny "skin." Therefore, it can be concluded that option third is correct.

My husband is a kid at heart so he absolutely loved spending an afternoon reminiscing with some of his favorite childhood games. There is no need to raid the piggy bank for quarters. A wristband ($13 per adult, $7 per child) allows you access to play unlimited games all day. You are welcome to come and go as you please so you can take breaks for lunch or to shop for soaps and sponges at the Sponge Docks.
My only complaint is that my husband insisted that we play all of the games as two players and he managed to crush my high scores on every game! Will definitely be returning to Replay Amusement Museum for a rematch soon!
Note to the parents: This is not an arcade that you can drop your children off at. All minors must be accompanied by an adult and anyone entering the building must pay for a wristband.

2. Explain what Gladwell means when he claims “you have to be intelligent enough” or “intelligence has a threshold” in relation to becoming an outlier.
Answer:
It means that an individual who believes to be an outlier has to be smart enough to have a perception of his position in the groups in which he lives, however this perception must be punctual and limited so as not to create problems and discomfort for himself.
Explanation:
This is because an outlier is an individual who is part of a group of other individuals, but who is different and does not fully fit the standard determined and observed by the members of that group. In this case, it is important that the outlier is smart enough to understand that it is different and that this group limits or harms him, so he can look for other groups that offer more advantages. However, this intelligence must be limited, as it is very difficult to establish a group that is fully adapted to the outlier and if that individual finds differences in any group that participates, he will be harmed, because he will live in complete isolation.

Practice a PASAFE + TEAR paragraph with the text you just read. (Education by Ralph Waldo Emerson)
Edgenunity
Answer:
In the essay education by Randolph W Emerson he talks about why the education system is damaged in his opinion on it in solution. The genre of this essay is an opinionated essay throughout the essay Emerson tends to have a condemning tone against the educator but towards the end it changes to a comforting and helpful tone. Emerson states “The natural method forever confutes our experiments, and we must still come back to it. The whole theory of the school is on the nurse's or mother's knee. The child is as hot to learn as the mother is to impart. There is mutual delight. The joy of our childhood in hearing beautiful stories from some skillful aunt who loves to tell them, must be repeated in youth” (Emerson 104). The reason behind the text is to critique the teaching/educational system established and how to effectively teach the pupils as well as change the way students are taught and treated by the teachers. The author wants the reader to do/think as a result of reading/viewing this piece, is view education differently because he wants them to know that education, based on his logic and perspective, is flawed, and he has solutions to fix that flaws.the audience and response is The group of readers that the piece is directed to is the teachers and students.
Explanation:
In his essay "Education," Ralph Waldo Emerson argues that education should not simply be about acquiring knowledge or skills, but rather about cultivating character and personal growth. To achieve this, Emerson suggests that education should focus on the development of a student's individual talents and interests, rather than trying to fit them into a predetermined mold. He also emphasizes the importance of self-reliance, encouraging students to think for themselves and question conventional wisdom. By doing so, Emerson believes that students will develop a strong sense of identity and purpose that will guide them throughout their lives.'
To implement Emerson's vision of education, schools and educators should adopt a PASAFE + TEAR approach. This would involve prioritizing the personal growth and development of each student, rather than simply teaching to standardized tests or conforming to societal norms. By emphasizing the unique talents and interests of each student, educators can help them discover their passions and cultivate a sense of purpose. Additionally, promoting self-reliance and critical thinking will enable students to develop the skills they need to succeed in life, rather than simply memorizing information.
Furthermore, a TEAR approach can also be implemented, where educators provide students with the tools and resources they need to pursue their interests and passions. This might include access to technology, mentorship programs, and extracurricular activities that allow students to explore their interests and develop new skills. By doing so, students will be better equipped to pursue their goals and find success in their chosen fields.
Overall, by adopting a PASAFE + TEAR approach to education, schools and educators can help students develop the skills, knowledge, and personal qualities they need to succeed in life. By prioritizing personal growth and self-discovery, educators can help students become confident, independent thinkers who are able to navigate the complexities of the modern world with purpose and meaning.
