Answer:
i. 3/5
ii. 2/5
Explanation:
Solving the problem by any of the students A, B and C is an independent event as solution by one does not restrict the other one from solving
However, the problem will be solved if even one of them solves the question
Now Probability of not solving the question by A, B and C are
PA (not solving a problem) - 1-1/3 = 2/3
PB (not solving a problem) - 1-1/4 = 3/4
PC (not solving a problem) - 1-1/5 = 4/5
ii) Probability of not solving - 2/3*3/4*4/5 = 2 *1/5 = 2/5
i) Probability of solving - 1- Probability of not solving
= 1 - 2/5 = 3/5
Answer:
wheat, rice, barley, oats, coffee, sugar cane, citrus fruits, melons and Kentucky bluegrass.
1. The world in spatial terms
The purpose of the first essential element of geography is to study the relationships between people, places, and environments by mapping information about them into a spatial context.
2. Places and regions
The purpose of the second essential element of geography is to show how identities and lives of individuals and peoples are rooted in particular places and in those human constructs called regions
3. Physical systems
The purpose of the third essential element of geography is to identify how physical processes shape the Earth’s surface and how they interact with plant and animal life to create, sustain, and modify ecosystems.
4. Human systems
The purpose of the fourth essential element of geography is to show how people are central to geography in that human activities help shape the Earth’s surface, human settlements and structures.
5. Environment and society
The purpose of the fifth essential element of geography is to show how the the physical environment is modified by human activities, largely as a consequence of the ways in which human societies value and use Earth’s natural resources.
6. The uses of geography
The purpose of the sixth essential element of geography is to show how the knowledge of geography enables people to develop an understanding of the relationships between people, places, and environments over time -- that is, of Earth as it was, is, and might be.
The closest star to the sun, Proxima Centauri, was recently found to have a planet in its habitable zone. Proxima Centauri is a main sequence star with spectral type m. It would habitable zone differs from the habitable zone of our sun Compared to our own, it would be far closer to Proxima Centauri.
<h3>What is the Proxima Centauri? </h3>
- Small, low-mass Proxima Centauri is a star in the southern constellation of Centaurus, 4.2465 light-years from the Sun.
- Its Latin name translates to "star closest to Centaurus."
- It is the known star that is closest to the Sun and was found in 1915 by Robert Innes.
<h3>Is the planet Proxima Centauri one?</h3>
- Super-Earth-sized exoplanet Proxima Centauri b revolves around a M-type star.
- It has a mass of 1.27 Earths, orbits its star in 11.2 days, and is 0.0485 AU away from it. In 2016, news of its finding was released.
