Game Arbitrage I

Consider the following group with the following teams. The contracts are given in the format of $\text{(Team, Time-0 Price)}$. The price of $0.67$ means that if the team wins, you will get paid $1$. If the team loses, you will get paid $0$.

$$\begin{align*} (\text{Team 1}, 0.84) \\ (\text{Team 2}, 0.73) \\ (\text{Team 3}, 0.25) \\ (\text{Team 4}, 0.15) \end{align*}$$

The group works as follows: 2 teams are guaranteed to make it out. Find the arbitrage. You are allowed to long or short contracts. You are also allowed to long or short bonds, which pay $1$ at expiry. Assume interest rates are $0$, so $Z_0 = 1$.
