Considering the given discrete probability distribution, it is found that there is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.
<h3>What is the discrete probability distribution?</h3>
Researching on the internet, it is found that the discrete probability distribution for the number of packs that Hugo buys is given by:
The probability that he buys fewer than 3 packs is given by:
P(X < 3) = P(X = 1) + P(X = 2).
Hence:
P(X < 3) = P(X = 1) + P(X = 2) = 0.2 + 0.16 = 0.36.
There is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

The correct answer is - B) the water quality of the stream.
By studying the fish populations and their well being, the watersheds, as well as the composition of the water, the scientists are trying to keep track of the situation of the quality of the water in the stream.
The fish populations, their activity, well being, are always a nice indicator about the water quality, as they live in it and are directly effected by any negative changes in the water quality.
The watersheds can also show a partial picture of the quality of the water in the streams, and that is because the water passes through them before entering the stream itself, so a clean and healthy watershed, often means good quality of the water.
The most relevant indicator of the quality of the water in the stream is still the testing of the water itself, where the water composition can be examined in detail thus to be determined its condition.

The role of oxygen in photosynthesis and in cellular respiration is: <em>Oxygen </em><em>is a product of </em><em>photosynthesis </em><em>and a reactant in </em><em>cellular respiration</em>.
<h3>What is Photosynthesis?</h3>
Photosynthesis is the process whereby green plants manufacture their food using energy from the sunlight, carbon dioxide and water to synthesize food in form of glucose and produce oxygen as a by-product.
<h3>What is Cellular Respiration?</h3>
Cellular respiration is a metabolic process in living organisms whereby glucose is broken down with the aid of oxygen, to release chemical energy.
Thus, the role of oxygen in photosynthesis and in cellular respiration is: <em>Oxygen </em><em>is a product of </em><em>photosynthesis </em><em>and a reactant in </em><em>cellular respiration</em>.
