There are currently 3 TV shows i want to watch!!! They all premiere in MAY.

BUT but BUT

I don't have access to the channels to watch them... darn. Pfftt.....

Our TV here has also been quirky... We set the channels and the next day, the channels change numbers. Reception has also been poor. At times, we really just watch the TV... with a blue screen. That is when we are too lazy to put a disc in to play.

Anyway, my latest hottest headache is U=1.5 E(r) - 1/3 A (std dev)*2

I JUST WANT TO KNOW IF MY ANSWER AND LINE OF THOUGHT IS CORRECT.
Who can enlighten me??? (I don't know if it's a mere 5 marks or an impt 5 marks)
