A car has many small parts such as the battery, radiator, brakes, axle, shock absorbers, etc.

<u>Explanation: </u>

These parts need repair from time to time. Our car does not work properly if any of such part is gone. This means if any part is damaged then the car will not move smoothly.

Suppose if the battery is dead then it will affect the voltage that the battery gives to the car. So we need to fix it. If the axle is broken, then driving can be hazardous. If the Radiator is leaking then the engine will overheat. This indicates the leakage of the radiator.

yaroslaw [1]

Answer:

a) Probability of prostrate cancer given a positive test is P(C|+) = 0.0213

b) Probability of cancer given a negative test is P(C|-) = 0.0161

c) Probability of prostrate cancer given a positive test is P(C|+) = 0.3137

d) Probability of cancer given a negative test is P(C|-) = 0.2553

Explanation:

Probability male patient has prostate cancer, P(C) = 0.02

Probability male patient does not have prostrate cancer P(C') = 1 - 0.02 = 0.98

Probability of a positive test given there is no cancer, i.e. P(false positive) = P(+|C') = 0.75

P(negative test given there is cancer) = P(false negative) = P(-|C) = 0.2

P(negative test given there is no cancer) is the complement of P(+|C') = P(-|C') = 1 - 0.75 = 0.25

Probability of positive test given there is prostrate cancer, P(+|C) is the complement of P(-|C), = 1 - 0.2 = 0.8.

a) Probability of prostrate cancer given a positive test is P(C|+)

According to Baye's theorem, P(C|+) = P(+|C)P(C)/P(+)

For P(+), we use the Law Of Total Probability: P(+) = P(+|C)P(C) + P(+|C')P(C')

P(+) = (0.8 * 0.02) + (0.75 * 0.98) = 0.751

Therefore, P(C|+) = P(+|C)P(C)/P(+)

P(C|+) = (0.8 * 0.02)/0.751 = 0.0213

b) Probability of cancer given a negative test is P(C|-)

According to Baye's theorem, P(C|-) = P(-|C)P(C)/P(-)

P(-) = P(-|C)P(C) + P(-|C')P(C')

P(-) = (0.2 * 0.02) + (0.25 * 0.98) = 0.249

Therefore, P(C|-) = (0.2 * 0.02)/0.249

P(C|-) = 0.0161

Part 2: Given the following;

Probability male patient has prostate cancer, P(C) = 0.3

Probability male patient does not have prostrate cancer P(C') = 1 - 0.3 = 0.70

Probability of a positive test given there is no cancer, i.e. P(false positive) = P(+|C') = = 0.75

P(negative test given there is cancer) = P(false negative) = P(-|C) = 0.2

P(negative test given there is no cancer) is the complement of P(+|C') = P(-|C') = 1 - 0.75 = 0.25

Probability of positive test given there is prostrate cancer, P(+|C) is the complement of P(-|C), = 1 - 0.2 = 0.8.

c) Probability of prostrate cancer given a positive test is P(C|+)

According to Baye's theorem, P(C|+) = P(+|C)P(C)/P(+)

For P(+), we use the Law Of Total Probability: P(+) = P(+|C)P(C) + P(+|C')P(C')

P(+) = (0.8 * 0.3) + (0.75 * 0.7) = 0.751

Therefore, P(C|+) = P(+|C)P(C)/P(+)

P(C|+) = (0.8 * 0.3)/0.765 = 0.3137

d) Probability of cancer given a negative test is P(C|-)

According to Baye's theorem, P(C|-) = P(-|C)P(C)/P(-)

P(-) = P(-|C)P(C) + P(-|C')P(C')

P(-) = (0.2 * 0.3) + (0.25 * 0.7) = 0.235

Therefore, P(C|-) = (0.2 * 0.3)/0.235

P(C|-) = 0.2553

An organizational structure is the official design of a company's staff. The structure clearly defines the relationships of subordination, the authority in decision-making, and the physical location of employees of various departments. A geographic organizational structure groups representatives of each functional department into units formed to serve a specific market or region. Geographic units can be highly effective if they are located within the regions that serve and employ workers in the local work environment.

According to the theory underlying the present-value formula, would a rational individual prefer to receive (a) $75 one year fro

laila [671]

Answer:

b. He will prefer $85 two years from now.

Explanation:

Before making the choice, lets first calculate the present values of these cash flows,

PV factors @ 10% are as follows,

Year 1 = 0.909

Year 2 = 0.8265

Year 3 = 0.7513

Present value of 75 = 75 * 0.909 = 68.175

Present value of 85 = 85 * 0.8265 = 70.25

Present value of 90 = 90 * 0.7513 = 67.617

A rational individual thus would chose $85 two years from now as it yields the max present value.

Hope that helps.
