2011 LEVER1 MOCK 一道题讨论

67. An equity manager conducted a stock screen on 5,000 U.S. stocks that comprise her investment universe. The results of the screen are presented in the table below.


Criterion
% of Stocks
Meeting Criterion
Price per share/Sales per share <1.25
35.0
Total asset/Equity ≤ 2.5
48.2
Dividends >0
58.6
Consensus forecast EPS >0
75.0
Meeting all 4 criteria simultaneously
10.8
If all the criteria were completely independent of each other, the number of stocks meeting all four criteria would be closest to:


A. 293.
B. 371.
C. 540

 

答案是把前面四个乘得出答案,那么给我Meeting all 4 criteria simultaneously干嘛,为什么这两个还不同?

题目自己做了假定,又没说算出来的要和实际结果一样。10.8是实际结果,算出来的是符合题目假定-completely independent的结果。
