a) Consider the 1 period binomial derivative pricing approach i) List two ways you could use to derive the formula for the price of the derivative ii) Using the two approaches noted in part (i) derive the price of a call option in each case b) Repeat part a(ii) but with respect to a put option c) Using the results in part (a) and (b), or otherwise, derive for an n period binomial tree, the formula for the price of i) A call option. ii) A put option
