Just need short definitions

Below is how each of the formulas will appear on the front of your exam booklet. You should know what is formula is and what it used for. x1- r PLL + PHH PLU(L) + PHU(H) N-x N 1-IN N-2x 2 - r N - x W ( p ) w ( p, w ) 1 w e-[- In(p)]w [ pw + ( 1 - p ) ( 1 1 / w W (PL, W)U(L) + W(PH, W)U(H) w(PL, W)AU(L) + w(PH, W)AU(H) To help familiarize yourself with the formulas ahead of time, you may find the following exercise useful. Fill in the blank on the left-hand side of each formula. On the right, make a brief note on the formula's definition or explanation or what it is used for, etc. Notes =xler 1 - r = PLL + PHH = PLU(L) + PHU(H) N-x N 2 -r N-2x N - x w (p) w ( p, w) = e-[- In(p)]w pw [ pw + (1-p) w] 1/w = W ( PL, W) U( L) + W (PH, W) U( H)
