Consider the following facts about Australian dollar: The current spot exchange rate is AUD1.36/USD. Over the next 180 days, there is a 20% probability that the AUD will strengthen relative to the dollar by 4%, and there is a 80% probability that the AUD will weaken by 7%. Required: a.

Suppose that the 180-day forward rate is AUD1.40/USD. ) What contract would you make to speculate in the 180-day forward market by either buying or selling AUD 10,000?
