Two friends board an airliner just before departure time. There are only ten seats left, two of which are aisle seats. How many ways can the two people arrange themselves in available seats so that at least one of them sits on the aisle? Solution total seats avaiable: 10 2= aisle , 8 = normal 1) both the friends get the aisle seats= 2P2= 2 ways 2) one gets an aisle seat while other gets the normal seat = 2P1x 8P1= 2x8 = 16 ways Total way s= 2 + 16 = 18 ways.

Two students, Ryan Wattenberg and Emma Bennett, are discussing the idea of convergence over coffee. Ryan considers convergence to be true in theory but impractical in the real world. He claims that most low-income developing countries are stuck in a cycle of poverty and so cannot catch up with developed countries. With increased globalization, Emma feels that the developing countries are growing and will converge with higher-income countries eventually. Zoey Smith, a friend of theirs, however thinks that the evidence on convergence is rather unclear. Despite the fact that developing countries are growing much faster than the developed countries, she thinks that they will not be able to catch up with the developed nations in the near future. Which of the following, if true, would strengthen Ryan\'s argument that developing countries will not catch up with developed countries? a. Most developed countries do not have similar resources endowments. b. Some of the fastest growing developing countries in the world also score well on many social indicators. c. Credit creation by the formal banking system in most developing countries has been falling or stagnant in the last five years. d. High population in developing countries, which for decades acted as a drag on growth, now forms a productive workforce. e. Most developed countries experienced a high degree of inequality in the initial phases of economic growth. Solution Ans = D The GDP growth rates of developing nations are on average more than those of developed nations.During the period 1965-99 , the average annual growth rate was 4.1 percent for the low- income nations, 4.2 percent for middle-income nations, and 3.2 percent for high-income nations . Does this imply that the developing nations would soon converge with the developed? Unfortunately, the growth patterns explained here do not imply that the world is on its path to “convergence\". Much faster population growth in most of the developing nations offsets the comparatively faster growth rates of GDP, leading to GDP per capita growth to be relatively low or perhaps even negative.Thus, the gap between the average GNP per capita between developing and developed nations has widened. During the past 40 years of the 20th century, the gulf between the average income of the richest 20 nations and that of the poorest 20 has doubled in size. Sustained economic growth of the developing nations is an essential instrument for reducing poverty and enhancing people’s standard of living. However, only economic growth is not enough. In few nations poverty worsened in spite of the overall economic growth, due to increased income inequality . This economic growth is socially unsustainable and causes social conflict, and is harmful to further growth. Also, fast economic growth may lead to fast environmental degradation, hampering the quality of life and thus decreasing economic productivity..

Two students independently attempt to solve a certain problem. The probability that A solves it is 1/10 and the probability that B solves it is 1/3. What is the probability that the problem will be solved? Solution Probability of A = 1/2 Probability of B = 1/2 Probability that A can solve the problem= 1/10 probability that B can solve the problem = 1/3 P(Problem will be solved)= (1/2)*(1/10)+(1/2)*(1/3) = 13/60 =0.2167.

Two key sources of economic growth have been due to increases in resources and increases in productivity. What factors will contribute to falling U.S. GDP growth rates into the future, and how would that impact you? Solution Increase in productivity and resources are the building block for any economy for that matter. One of the prime reasons why US economy developed in the last century is because of the importance given to trade and commerce as also industrialisation and optimum usage of available resources. US had and still has abundance of metals and coal, the driving factors for any industry. American economy is also one of the most open and most traded with economies with every single nation being its trade partner. This is also understandable since nearly 40% of capital used in US is imported. Then during 1940s and 1950s, there was a shift in labour class as more and more people starting enrolling in higher education. Gradually, labour got more skilled and productive. Now, it is eactly the same factors that would result in a falling GDP and growth rate. Although this would not really happen since the cycle of development is permanent and might take generations to hit bottom rock, its several factors that would result in falling productivity to be specific. Resources too should be counted for since their exhaustion can lead to some serious economic disasters. Imagine what it might be if all coal reserves would suddenly vanish. You will have each and every industry coming to a halt, there would be continuous electricity cuts, productivity would go at zero levels and people\'s income would hit rock bottom. So definitely resources play one of the most crucial parts when it comes to growth rates. Take the case of productivity. Its the people who contribute towards productivity. The latter is decided by education levels, population and taxation. Higher education simply leads to higher levels of productivity. Economic history of US stands as an evidence. The higher the population, lower is the productivity but only to certain limit. Since employment levels depend on population, a scarcity in the latter cannot lead to higher growth. Similarly, too high population leads to lower productivity and per capita income. Lastly is taxation, something that is still being debated. too high tax levels act as deterrents to income growth, too low taxes inhibit economic growth..

Two power generating units A and B operate in parallel to supply the power requirements of a small city. The probability of failure of each unit is 0.1, where the probability that both fail is 0.02. What is the probability that when there is a power failure only one of the two units will have failed? Solution P(only one of them has failed) = P(Failure of A) + P(failure of B) - 2P(Failure of both) = 0.1 + 0.1 - 2*0.02 = 0.16.

two frieends are to meet at the library. Each arrives at independently and randomly selected times wiithin afixed 1- hour period. Each agree to wait no more than 15 minutes for the other. find the probability that the meet. Solution Let\'s take n = 2 variables ( the two people\' s arrivals ) ; d = 60 min ( the entire period within they arrive) ; t = 15/d = 15/60 = 0.25 ( fraction of entire period they wait ); The probability they meet is : p = nt^(n-1) - (n-1)t^n = 2*0.25^1 - 1*0.25^2 = 0.4375.

Two people took turns tossing a fair die until one of them tossed a 6. Person A tossed first, B second. A third, and so on. Given that perosn B threw the first 6, what is the probability that B obtained the first 6 on her second toss (that is on, on the fourth toss overall)? Solution Geometric pmf -> x = n, p(1-p)^n P[6] = probability of rolling a 6 = 1/6 P[x = 4] = (1/6)(5/6)^3 = 125/1296 = .09645.
