<h3>Explanation:</h3>
In each case the expected value is the sum of products of value and its probability. (This is the definition of expected value.)
a) 1·0.3 +2·0.45 +3·0.05 +4·0.1 +5·0.1 = 2.25
b) 0·0.05 +1·0.15 +2·0.35 +3·0.25 +4·0.15 +5·0.05 = 2.45

It is usually convenient to let a machine do the arithmetic, especially when the lists are long.
Here, you may notice there are only 5 contributors to the total for the second question. The first contributor for that question would be 0·0.05 = 0, so adds nothing to the total. Leaving it out makes the table sizes match, so makes the two problems easier to work with this calculator.
Answer:
The answer is A)
Explanation:
Trees absorb carbon dioxide and produce oxygen. Fewer trees can lead to a high concentration of carbon dioxide in the atmosphere. If the forest or felled trees are burned, which they often are, it released carbon dioxide into the atmosphere. Carbon dioxide is the most common gas that is released by humans. That means the anthropogenic cause of enhanced climate change will be increased. Floods will increase as less interception and less vegetation storage is causing the ground to become saturated quickly and this leads to floods. The water cycle in the are will be disrupted and so to will the nutrient cycle as there are fewer plants and fewer animals to provide nutrients.
It will cause a change in the quantity demanded. There will be the same demand, but if the price goes up less people will buy the papayas.
