13. There are 15 boys and 10 girls in a class. If three students are selected at random, what is the probability that 1 girl and 2 boys are selected?​

Answers

Answer 1

Answer:

21/46

Explanation:

Combinations of 3 students from among 25 = 25!/(22!)(3!) = 2,300.

Combinations of 1 girl (G) from among 10 girls = 10!(9!)(1!) =10.

Combinations of 2 boys (BB) from among 15 boys= 15!/(13!)(2!) = 105.

Combinations of 1 girl and 2 boys (GBB) = 10*105 = 1,050.

Probability as requested = 1,050/2,300 = 21/46 = .456521739…~ 45.7%.

You could also calculate the probability as (10/25)*(15/24)*(14/23)*](3!)/(2!)] = .456521739…~ 45.7%. The (3!)/2!) factor accounts for the number of ways of probability selection: GBB has 3! arrangements but the B’s are interchangeable.

From this, we can conclude that: the correct answer is option B. There are infinite magical names.

How did we arrive at this assertion?

From the given information, we know that the first magical name has five letters and that no name formed by an even number of letters is magical. We can use this information to eliminate some of the options:

A. If there is only one magical name and it has five letters, then no other name can be magical, so this option contradicts the statement that there are infinite magical names. Therefore, option A is incorrect.

B. This option is consistent with the information given, as there is no limit on the number of magical names that can be formed by an odd number of letters. Therefore, option B is correct.

C. This option contradicts the statement that the first magical name has five letters. Therefore, option C is incorrect.

D. This option suggests that there is a last magical name, but since there are infinite magical names, there is no last name. Therefore, option D is incorrect.

E. This option is not related to the given information, so it cannot be used to draw any conclusions about magical names. Therefore, option E is incorrect.

In conclusion, the correct answer is B. There are infinite magical names.

Discuss THREE ways in which the media's portrayal of women as vulnerable members of society could lead to greater instances of violence towards women.

Answers

Answer: View answer in explanation below.

Explanation: The media's portrayal of women as vulnerable members of society can contribute to violence towards women in several ways:

Normalizing violence against women: Media often portrays women as victims of violence and crime, which can create a sense of normalization around violence against women. This can make it easier for perpetrators to justify their actions and can make it harder for society to recognize and respond to violence when it occurs.

Reinforcing gender stereotypes: Media representations of women often reinforce traditional gender roles and stereotypes, portraying women as weak and passive. This can contribute to a culture that devalues and marginalizes women, making it easier for perpetrators to justify violence and abuse.

Creating unrealistic expectations of women: The media's portrayal of women as vulnerable and helpless can create unrealistic expectations of women, leading to victim-blaming and contributing to a culture of disbelief when women come forward with stories of abuse or violence. This can make it harder for women to seek help and support when they need it and can contribute to a sense of isolation and shame.

Overall, the media's portrayal of women as vulnerable can contribute to a culture that devalues and marginalizes women, making it easier for perpetrators to justify violence and abuse. It is important for the media to recognize their role in shaping societal attitudes and to work towards more positive and empowering representations of women.

Excluding certain tenants in a four-family dwelling where one unit is owner-occupied and the Juanita and Neha are considering contributing toward the creation of a water fountain. Each can choose whether to contribute $300 to the water fountain or keep that $300 for a weekend getaway.Since a water fountain is a public good, both Juanita and Neha will benefit from any contributions made by the other person. Specifically, every dollar that either one of them contributes will bring each of the $0.70 of benefit. For example, if both Juanita and Neha choose to contribute, then a total of $600 would be contributed to the water fountain. So, Juanita and Neha would each receive $420 of benefit from the water fountain, and their combined benefit would be $840. This is shown in the upper left cell of the first table.Since a weekend getaway is a private good, if Juanita chooses to spend $300 on a weekend getaway, Juanita would get $300 of benefit from the weekend getaway and Neha wouldn't receive any benefit from Juanita's choice. If Juanita still spends $300 on a weekend getaway and Neha chooses to contribute $300 to the water fountain, Juanita would still receive the $210 of benefit from Neha's generosity. In other words, if Juanita decides to keep the $300 for a weekend getaway and Neha decides to contribute the $300 to the public project, then Juanita would receive a total befit of $300+$210=$510, Neha would receive a total benefit of $210, and their combined benefit would be $720.
