I'm having issues proving the following which should be simple: If A and B are mutually exclusive, prove Pr(A) <= Pr(B') From the statement about being mutually exclusive, I know A \cap B = \phi Therefore we have P(A \cap B) = Pr(A) + Pr(B) Also, A = A \cap B' and B = A' \cap B...

Ok, the first one is wrong. The voltage at point A for figure one should be around 2.62V because this is what I actually measured in the lab. I don't get it, this should just be a simple voltage rule right? How come when I apply it I don't get the right voltage using 5*(1/21) ?

Homework Statement We're learning about superposition in class right now and I'm having some trouble visualizing how to make simplifications using series/parallel connections. I attached the picture of the circuit and we're being asked to solve for the voltages and currents through the...

so the 500 and 1k resistors are in parallel i believe? which would give me a 333.3k resistor right? then that equiv resistor is pretty much in series with the 2 k resistor... which would mean the 1mA current is also flowing through the 333.3K resistor, then i could just use ohm's law to get...

i attached a picture of a circuit and my question is what is the voltage reading for the the indicated terminals... what I am thinking is that 500 and 2k ohm resistor in series... and then combine that in parallel with the 1k resistor? then use ohms law?
