marbles numbered from 1 to 12 are put in a bag. if marbles are not put back into the bag after being drawn, what is the probability of drawing two prime numbers in a row?

Answers

Answer 1

Answer:

[tex]P = \frac{1}{11}[/tex]

Explanation:

Given

[tex]Marbles = 12[/tex]

Selection: Without replacement

Required

The probability of selecting 2 primes

Between 1 and 12, the prime digits are: 3, 5, 7 and 11

i.e. 4 prime digits

When the first marble is selected, the probability that it will be prime is:

[tex]P(1) = \frac{4}{12}[/tex]

 

Since it is a selection without replacement, there are 3 primes left and 11 marbles in total.

The probability of selecting another prime is:

[tex]P(2) = \frac{3}{11}[/tex]

The required probability is:

[tex]P = P(1) * P(2)[/tex]

[tex]P = \frac{4}{12} * \frac{3}{11}[/tex]

[tex]P = \frac{1}{11}[/tex]

Answers

Answer: B

Explanation:

Japan backs a democracy after ww2 so that means the people can vote. China is communist and does not listen to its people

Correct Answer: D : Women Face Discrimination

Explanation:

The Explanation is: Rapid modernization has enabled China to provide its citizens with improved living standards and increased economic opportunities. Yet this process has yielded uneven gains between men and women. Pronounced wage gaps and imbalanced political representation are just two of the many issues hindering gender equality in China. Working to address these inadequacies is essential for China as it continues its socio-economic development.China’s constitution guarantees women “equal rights with men in all spheres of life,” and over the last several decades, women in China have enjoyed some notable gains. Life expectancy and literacy rates, for instance, have risen as China’s economy has developed. This progress, however, have been outpaced by the rest of the world. China’s ranking in the index fell sharply from 63rd out of 115 countries in 2006 to 103rd out of 149 countries in 2018.Access to healthcare and positive health outcomes are key measures of gender equality. Similar to other developing countries, as China has grown richer its citizens have enjoyed a higher life expectancy. Chinese women born in 2016 can expect to live 77.8 years, an increase of 4.2 years from 2000 and 9.5 years from 1980. While female life expectancy in China has surpassed the global average since 1970, it still falls short of high-income neighbors like Japan (87.1 years) and South Korea (85.2 years).

What is Age of Imperialism?

The Age of Imperialism began around 1870, when modern, reasonably developed nations took over less developed territories, colonized them, or influenced them in order to extend their own authority.

Many European countries had an increasing interest in colonies as sources of raw materials and new markets, as well as prospective destinations for excess population and administrators who could not be accommodated at home. Individual opportunities for adventure and profit were also plentiful.

Attitudes like the one articulated in the paragraph led most directly to European powers' quest for overseas territories in the late 1800s. Therefore, option 1st is correct.
