GWD-12-Q6:

Q6:

A box contains 10 light bulbs, fewer than half of which are defective.  Two bulbs are to be drawn simultaneously from the box.  If n of the bulbs in box are defective, what is the value of n?

(1)
                
The probability that the two bulbs to be drawn will be defective is 1/15.

(2)       The probability that one of the bulbs to be drawn will be defective and the other will not be defective is 7/15.

            

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.

                                                                                Answer:

 

 

Q23 to Q26:

      Why firms adhere to or deviate

      from their strategic plans is poorly

      understood.  However, theory and

Line      limited research suggest that the

  (5)      process through which such plans

emerge may play a part.  In particular,

top management decision-sharing

consensus-oriented, team-based

decision-makingmay increase the

 (10)      likelihood that firms will adhere to their

plans, because those involved in the

decision-making may be more com-

mitted to the chosen course of action,

thereby increasing the likelihood that

 (15)      organizations will subsequently adhere

to their plans.

      However, the relationship between

top management decision-sharing and

adherence to plans may be affected

 (20)   by a firm’s strategic mission (its fun-

      damental approach to increasing

      sales revenue and market share, and

generating cash flow and short-term

profits).  At one end of the strategic

 (25)      mission continuum, “build” strategies

are pursued when a firm desires to

increase its market share and is willing

to sacrifice short-term profits to do so.

At the other end, “harvest” strategies

 (30)   are used when a firm is willing to

sacrifice market share for short-term

profitability and cash-flow maximiza-

      tion.  Research and theory suggest

that top management decision-sharing

 (35)
                     may have a more positive relationship

with adherence to plans among firms

with harvest strategies than among

firms with build strategies.  In a study

     of strategic practices in several large

 (40)
                
firms, managers in harvest strategy

scenarios were more able to adhere

to their business plans.  As one of the

managers in the study explained it,

this is partly because “[t]ypically all a

 (45)      manager has to do [when implementing

a harvest strategy] is that which was

done last year.”  Additionally, man-

agers under harvest strategies may

have fewer strategic options than do

 (50)   those under build strategies; it may

therefore be easier to reach agree-

ment on a particular course of action

through decision-sharing, which will

in turn tend to promote adherence

 (55)   to plans.  Conversely, in a “build”

strategy scenario, individual leader-

ship, rather than decision-sharing,

may promote adherence to plans.

Build strategies—which typically

 (60)      require leaders with strong perso-

nal visions for a firm’s future, rather

than the negotiated compromise

of the team-based decision—may

be most closely adhered to when

 (65)      implemented in the context of a clear

strategic vision of an individual leader,

rather than through the practice of

decision-sharing.

Q23:

Which of the following best describes the function of the first sentence (lines 17-24) of the second paragraph of the passage?

          

A.   To answer a question posed in the first sentence of the passage about why firms adopt particular strategic missions

B.    To refute an argument made in the first paragraph about how top management decision-making affects whether firms will adhere to their strategic plans

C.   To provide evidence supporting a theory introduced in the first paragraph about what makes firms adhere to or deviate from their strategic plants

D.   To qualify an assertion made in the preceding sentence (lines 6-16) about how top management decision-making affects the likelihood that firms will adhere to their strategic plans

E.    To explain a distinction relied on in the second paragraph (lines 17-68) regarding two different kinds of strategic missions

Answer: e

WHY NOT D

12-Q6

第一个小于自然概率肯定不成立啦

第二个  假设为N个    则被抓取的两个中一个是D的概率是    n*(10-n)*2/(10*9)=7/15  记得  n=3,7由于 n小于一半  所以n为3
