If A and B are independent, prove that \bar A, \bar B are independent.

Could someone help me start this. It's due tomorrow. I managed to prove that \bar A [/tex] is independent with B and that \bar B is independent with A, but I can&#039;t get the last one (the question I put above). Just a little nudge would be good. I&#039;ve been going in circles trying stuff, from De Morgans law, to every identity I can think of.<br /> <br /> Thanks

What are you using as the definition that A and B are independent?

For A and B being independent,
P[AB]=P[A]P
 
The professor posted the solution. Later :)
 
Prove $$\int\limits_0^{\sqrt2/4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx = \frac{\pi^2}{8}.$$ Let $$I = \int\limits_0^{\sqrt 2 / 4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx. \tag{1}$$ The representation integral of ##\arcsin## is $$\arcsin u = \int\limits_{0}^{1} \frac{\mathrm dt}{\sqrt{1-t^2}}, \qquad 0 \leqslant u \leqslant 1.$$ Plugging identity above into ##(1)## with ##u...
