Answer:
A skilled broker will be right at 60% of time compared to 50%
Explanation:
Solution
Given that:
Now,
Let X be represented as = number of correct predictions/outcomes
X foll binomial distribution with n = 3 and p = 0.5 for broker who use a toss coin
Thus,
P(X = 3) = p^3 = 0.5^3 which gives us = 0.125
So,
For a skilled broker, Y goes with the binomial distribution with n = 3 and p is = 0.6
Then,
P(Y = 3) = 0.6^3 = 0.216
We can therefore conclude who is skilled broker by making large number of observations
Hence, we say that a skilled broker will be correct 60% of time compared to 50%

Answer:
0.0042 is the probability of the stick's weight being 2.33 oz or greater.
Explanation:
We are given the following information in the question:
Mean, μ = 1.75 oz
Standard Deviation, σ = 0.22 oz
We are given that the distribution of drumsticks is a bell shaped distribution that is a normal distribution.
Formula:
P(stick's weight being 2.33 oz or greater)
P(x > 2.33)
Calculation the value from standard normal z table, we have,
0.0042 is the probability of the stick's weight being 2.33 oz or greater.
Answer:
A. wastefulness - production inside PPC ; B. Economy growth - PPC shift outwards/rightwards ; C. Economy at Productive Efficiency - production on PPC ; D. Unattainable Production- Outside PPC
Explanation:
PPC is graphical representation of production combinations that an economy can produce, given resources & technology.
PPC is based on assumption : That resources are best efficiently utilised. So, all product combinations ON PPC reflect 'Economy is at Productive Efficiency'
All production points INSIDE PPC reflect inefficient utilisation of resources i.e 'Wastage'
Points OUTSIDE PPC are 'Unattainable Product Combinations'- as they are beyond economy's best optimum production, given resources & technology.
'Economic growth' is increase in resources &/or technology which increases economy's production potential and PPC curve SHIFTS rightwards or outwards.
Answer:
Gadget will have higher earning.
Explanation:
Price Earning Ratio is the ratio of Market price to the earning per share. PE Ratio measure the effect of earning over the market price of the company.
Widget
Stock Price = $30
Earning per share = $2
PE ratio = $30 / $2 = 15 times
Gadget
Stock Price = $30
Earning per share = $2
PE ratio = $20 / $1 = 20 times
Gadget will have higher earning.
