Equation issue

  1. Oct 29, 2005 #1
    Hello, could use a hand with this,
    (100) (.2)X(.8) 100-X =

    This equation is written in this format and I can't remember wether I should devide 100 by 2 or use the 2 as part of the multiplication. Thanks

    Is this what you are trying to write out?

    (100)(0.2x)(.8)(100 - x) = 2

    I am confused by your grouping here.

    if you can clear it up a bit I think I can help you out.

    Please to do not double post! You posted this in the homework section and I responded there.

    (This is a binomial distribution problem.)
