Answer:
-0.352
Explanation:
Total number of raffle tickets sold = 14,500
1 grand prize of $6,600, 3 prizes of $800, 3 prizes of $65 and 10 prizes of $20.
Therefore,
Probability of winning 1 grand prize of $6,600 =
Probability of winning 3 prizes of $800 = 
Probability of winning 3 prizes of $65 = 
Probability of winning 10 prizes of $20 = 
Expected value:
![=[(\frac{1}{14,500}\times 6,600) + (\frac{3}{14,500}\times 800) + (\frac{3}{14,500}\times 65) + (\frac{10}{14,500}\times 20)] - 1](https://tex.z-dn.net/?f=%3D%5B%28%5Cfrac%7B1%7D%7B14%2C500%7D%5Ctimes%206%2C600%29%20%2B%20%28%5Cfrac%7B3%7D%7B14%2C500%7D%5Ctimes%20800%29%20%2B%20%28%5Cfrac%7B3%7D%7B14%2C500%7D%5Ctimes%2065%29%20%2B%20%28%5Cfrac%7B10%7D%7B14%2C500%7D%5Ctimes%2020%29%5D%20-%201)

= 0.648 - 1

Answer:
a shortage would arise since quantity demanded would exceed the quantity supplied
Explanation:
The law of demand states an inverse relationship between price of a good and it's demand.
In the given case, per month rental for rooms has significantly reduced for students. This would result into an immediate increase in demand for the rooms. Now since, the rooms available are limited in number, a shortage would arise.
Owing to such a shortage, a possibility would arise wherein students who do not require such rooms may avail such rooms at $500 and subsequently let out the rooms to outsiders at anything below $900 thereby earning a profit.
Answer:
D. there are reasonable substitutes for most goods.

A monopoly is when there is only one firm operating in the industry. There are also no subsituites for goods and services produced by the monopoly. The monopoly sets the price for his product and earns economic profit in the long and short run.
There aren't a lot of monopolies in the real world because most goods have substitutes. Therefore, consumers can substitute the monopoly product for another product and there isn't just one firm operating in the industry.
