    Financial Physics - Probability of Winning

    Alright let's see if I got this. Notation was killing me so I changed it: ∏WW=∏1, ∏WL=∏2, ∏LW=∏3, ∏LL=∏4. Using these equations: ∏1 = ∏1P4 + ∏3P2 --Equation 1 ∏2 = ∏1(1-P4) + ∏3(1-P3) --Equation 2 ∏4 = ∏2(1-P3) + ∏4(1-P1) --Equations 3 ∏1 + ∏2 + ∏3 + ∏4 = 1 -- Equation 4 ------...

    Financial Physics - Probability of Winning

    The only thing that we did in class that could relate to this would be the binomial tree model. So after looking up Markov Chain and reading a bit it makes more since but I am still struggling. Here is an attempt: So the underlining reasoning is that S0P = S1 Where P is the transition...

    Financial Physics - Probability of Winning

    Homework Statement Question: In game A the probability of winning at time t is determined by success (in any game) at the previous two timesteps t-2 and t-1. A win (W) earns one unit of cash, and a loss (L) results in paying one unit of cash. Following a sequence of outcomes (L;L) at time...

    Poynting Vector - Finding stored energy per unit length of a solenoid

    Homework Statement long solenoid of n turns per unit length is wound upon a cylindrical core of radius a and relative permeability. The current I through the solenoid is increasing with time t at a constant rate. Obtain expression for the rate of increase of stored energy per unit length...
