Question 1.

These questions consist of two propositions as well: a statement and a reason, nations by the word why. You must examine the veracity of each proposition and the theoretical relationship that unites them.

Statement:

The deterministic models of decision, are known with certainty all the data of the reality that represent because if one or more data are referred to only in terms of probability, the model is called, probabilistic, random or stochastic.

Select one:

a. The affirmation and the reason and reason are true, but the reason is not a correct explanation of the statement.  Correct Answer
b. The affirmation and reason are true and the reason is a correct explanation of the statement. 
c. The statement is false, but the reason is a proposition true.
d. The statement is true, but the reason is a false proposition.

Question 2

This question consists of two propositions as well: a statement and a reason, nations by the word why. You must examine the veracity of each proposition and the theoretical relationship that unites them.

Statement:

The following decision tree presents the states of nature and their probabilities to decide if you do or do not develop a new product, taking into account whether or not the hiring of a consultant of a market research firm:

Where:

A1: Develop the new product.
A2: Not to develop the new product.
A, B, C: States of nature and their probabilities.
A: Sell high.
B: Sell media.
C: Sell low.
AP, BP, Cp: Likely to reliability.

The expected value in the node 3 corresponds to a mathematical calculation of 1870 monetary units because the expected value is the sum of the states of nature multiplied by the odds associated with each one of its branches.

Select one:

a. The affirmation and reason are true and the reason is a correct explanation of the statement.
b. The statement is false, but the reason is a proposition true.  Correct Answer
c. The affirmation and reason are true, but the reason is not a correct explanation of the statement. The correct answer is: The affirmation and reason are true and the reason is a correct explanation of the statement.
d. The statement is true, but the reason is a false proposition.

Your answer is Correct.
The correct answer is: The statement is false, but the reason is a proposition true.
