Use the binomial method to determine the value of compound Call on a Put

option, where both the Call and the Put are of European style. The current time

is $t=0$ and the current value of the underlying, which does not pay dividends,

is $S(0)=50.$ The Put option expires at $T_2=3$ with exercise price $E_2=50,$

and the Call option expires at time $T_1=1$ with $E_1=10.$ The interest rate is

$r=0\mathrm{.}1.$ Use a time step of $t=1.$ Consider the case of $ud=1$ and suppose

the volatility is $=0\mathrm{.}3.$ Perform all calculations using a minimum of $4$ decimal

places of accuracy.
