Answer:
The answer is below
Explanation:
A What is the probability that all 4 selected workers will be the day shift?
B What is the probability that all 4 selected workers will be the same shift?
C What is the probability that at least two different shifts will be represented among the selected workers.
A)
The total number of workers = 10 + 8 + 6 = 24
The probability that all 4 selected workers will be the day shift is given as:
![P_a=\frac{C(10,4)}{C(24,4)}= \frac{210}{10626}=0.0198](https://tex.z-dn.net/?f=P_a%3D%5Cfrac%7BC%2810%2C4%29%7D%7BC%2824%2C4%29%7D%3D%20%5Cfrac%7B210%7D%7B10626%7D%3D0.0198)
![C(n,r)=\frac{n!}{(n-r)!r!}](https://tex.z-dn.net/?f=C%28n%2Cr%29%3D%5Cfrac%7Bn%21%7D%7B%28n-r%29%21r%21%7D)
B) The probability that all 4 selected workers will be the same shift (
) = probability that all 4 selected workers will be the day shift + probability that all 4 selected workers will be the swing shift + probability that all 4 selected workers will be the graveyard shift.
Hence:
![P_B=\frac{C(10,4)}{C(24,4)}+\frac{C(8,4)}{C(24,4)}+\frac{C(6,4)}{C(24,4)}=0.0198+0.0066+0.0014=0.0278](https://tex.z-dn.net/?f=P_B%3D%5Cfrac%7BC%2810%2C4%29%7D%7BC%2824%2C4%29%7D%2B%5Cfrac%7BC%288%2C4%29%7D%7BC%2824%2C4%29%7D%2B%5Cfrac%7BC%286%2C4%29%7D%7BC%2824%2C4%29%7D%3D0.0198%2B0.0066%2B0.0014%3D0.0278)
C) The probability that at least two different shifts will be represented among the selected workers (
)= 1 - the probability that all 4 selected workers will be the same shift(
)
![P_C=1-P_B\\\\P_C=1-0.0278\\\\P_C=0.972](https://tex.z-dn.net/?f=P_C%3D1-P_B%5C%5C%5C%5CP_C%3D1-0.0278%5C%5C%5C%5CP_C%3D0.972)

Answer:
Explanation:
Pizza quantity Change = 60-50 = 10
Income change = $12000 - $10000 = $2000
Mid point of Quantity of Pizza = (50+60)/2 = 55
Mid point of income = ($12000 + $10000)/2 = $11000
Income elasticity = 10*11,000/2000*55 = 110,000/110,000=1
Pizza is a unit elastic normal good, because percentage change in income = % change in pizza quantity
Answer:
4.5% annual interest.
Explanation:
Assuming that we are talking about a specific Savings Account then we can say that the average APY on a savings account such as HSBC savings is 2.5% per year. On the other hand, the stock market has an average APY of 7% annually. Therefore, in order to find how much you would lose by putting your money in a savings account, we would need to subtract the savings account APY from the stock market APY.
7% - 2.5% = 4.5%
We can see that what you would lose in opportunity cost is 4.5% annual interest.
