Let St be the price of one share of a particular company at time t. If the price St+1 at time t+1 can either take the value of uSt with probability p1 (where u>1), remain the same with probability p2 or go down to dSt with probability 1-p1-p2 (where 0<d<1), create a Matlab function called … that simulates {St} from t=0 to t=20 for given u,d,p1 and p2 and plots St against t. Hence, by counting the number of paths; calculate the probability that S6=S0(u^2)(d^3)
using the command RAND
