Hello, could use a hand with this,
(100) (.2)X(.8) 100-X =
2

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

Is this what you are trying to write out?

[tex] (100)(0.2x)(.8)(100 - x) = 2[/tex]

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

(This is a binomial distribution problem.)
