Logic propositions Help

  1. May 10, 2005 #1
    Hello to all. Could anyone give me some insight on the following problems? I put my answers down, but not sure if they are correct. Thanks for any help you may provide.

    A. Express each of the following propositions as equations or inequalities, representing each class by the first letter of the English term designating it, and symbolizing the proposition by means of a Venn diagram:

    1. All merchants are speculators. Answer: MS=0 (with bar over the "S")
    2. Some stockholders who advise their customers about making investments are not partners in companies whose securities they recommend. Answer: SP=0 (bar over "P" & line thru the equal sign)
    3. No pipelines laid across foreign territories are safe investments. Answer: PS=0
