So here is the problem:
Now what seems logical to me is first choose 1 of the 10 non-performing and then choose 4 from the remaining 139 chips.
What is wrong with my logic here? I don't get the answer the book gets (130,721,752), and instead get 148, 916, 260.
Well, as given in our book, the syntax they want us to use is the following:
(*x | R : P)
R = Range, P = Body, * = operator/function, x = variable(s). The ':' is also used to represent type (i.e. x : Z = x of type integer).
In class my professor just left out R or made it "true" when he...
Ya, I was wondering that exact same thing sylas. My textbook talks a lot about how English is so ambiguous, so I'm going to assume that whether this applies to one student or all students is open to my interpretation ;).
Homework Statement
I actually have to problems I would just like someone to confirm for me. I have several other problems similar to these, and I don't want to waste time in case I do not understand the fundamentals. Anyway:
a) Define suitable predicates and functions and then formalize...
Well, according to this truth table, it's right:

I can't figure out how to prove this algebraically though.
Okay, so I'm stuck at a step of a much bigger problem where I have to simplify a boolean function.
Homework Statement
Here is where I'm stuck, I have to change the left hand side to the right hand side. How do I prove this with the rules of boolean algebra?
CA + CB + B'A = CB + B'A...
Nope, the book says what I wrote. I'm not surprised though; I've found several typos in the questions in this particular textbook...
Thanks a lot for the clarification, I thought maybe I was missing some obscure rule :p.
Also, thanks for showing how to use the LaTex code properly :)
Homework Statement
Use the given matrices to find (AB)^-1
(These are 2 X 2 matrices, please ignore the fraction bar in between the top and bottom elements. I can't figure this stupid latex piece of crap out)
A^{-1} = \left(\frac{\frac{1}{2}}{\frac{-1}{2}} \ldots...
Okay, great, that yields a correct answer :)
If you don't mind rl.bhat, could you show me how you derived that (D/485)/d?
EDIT:
Oh wait, never mind, I just realized that you just used s = (radius)*(theta). Thanks again!
