AI Thread Summary
The discussion revolves around a dilemma between four options, with a preference for option D. The participant expresses uncertainty about whether the solution should consider only parts of B and C or all of C excluding A. They reference a specific probability equation but acknowledge a lack of confidence in its correctness. A suggestion is made to review De Morgan's law to clarify the confusion regarding the equation. The conversation emphasizes the need for a deeper understanding of the concepts involved in the options presented.

Why do you think it could be either A or D? What have you learned about complements and intersections? You could have just been guessing, so you should post some more work.

-D
 
is hard to post all the work here.
but p(AnB^c)^c n C=P(A^cnB) n C.
this why i almost sure it D.
i tell you why i am not sure if is D, well because i am not sure if is need to be only the part in B and C except the part A or the part in all C except the part A and C as showing in option A.
so can you help me with that ?

thanks.
 
Your equation in the second line is not correct, look up De Morgan's law again.
 

Thread 'Family of lines that are at a distance of 5 from the origin'

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...

Thread 'Making the denominator of a certain fraction real'

Essentially I just have this problem that I'm stuck on, on a sheet about complex numbers: Show that, for ##|r|<1,## $$1+r\cos(x)+r^2\cos(2x)+r^3\cos(3x)...=\frac{1-r\cos(x)}{1-2r\cos(x)+r^2}$$ My first thought was to express it as a geometric series, where the real part of the sum of the series would be the series you see above: $$1+re^{ix}+r^2e^{2ix}+r^3e^{3ix}...$$ The sum of this series is just: $$\frac{(re^{ix})^n-1}{re^{ix} - 1}$$ I'm having some trouble trying to figure out what to...
