<span>The positions north and south are measured in degrees latitude. Opposite to this, west and east of greenwich is measured in degrees longitude. That's why when determining a position you would say that something is 40 degrees north and 74 degrees west, and this exact position would point to New York City. The first number is how north above the equator it is and the second number how much west from Greenwich it is. </span>
Given:
62% of the residents visit Comet Mall.
73% of the residents visit Star Mall.
48% of the residents visit both malls.
To find:
The probability that a resident chosen at random shops at either Comet Mall or at Star Mall.
Solution:
Let A be the event that the residents visit Comet Mall and B be the event that residents visit Star Mall. Then, we have
We need to find the probability that a resident chosen at random shops at either Comet Mall or at Star Mall. It means, we have to find the value of 
.
We know that,
On substituting the given values, we get
Therefore, the probability that a resident chosen at random shops at either Comet Mall or at Star Mall is 87%.

Answer:
B. local water contamination
D. destruction of ecosystems
Explanation:
The mining, be it a surface one or underground one, has several negative impacts on the surrounding area. Two common negative impacts of both types of mining are contamination of the local waters, as well as the destruction of ecosystems.
The waters get heavily polluted with toxic chemicals pretty much always ad everywhere where there is mining. The main reason for this is that the nus-products from the mining are released into the waters. This causes high level pollution of the waters, thus making it not good for anything, and the aquatic life in the waters dies out rapidly.
The fact that the waters are heavily polluted means that everything that comes in touch with them becomes heavily polluted as well. Also, apart from releasing chemicals in the waters, the mining requires space, so the area is cleared out, and after that lot of toxic material is disposed on it. The majority of the plants can sustain that, so they die out, and since they are the basis of the ecosystems, the animals die out as well.
