Question 178983
<font face="Times New Roman" size="+2">

Since ALL of the baskets are incorrectly labeled, you know without testing anything that:


The basket labeled APPLES actually contains all oranges or a mixture.


The basket labeled ORANGES actually contains all apples or a mixture.


The basket labeled APPLES AND ORANGES contains either all apples or all oranges.


If you select one piece of fruit from the basket labeled APPLES AND ORANGES and:


If it is an apple, you know that the basket labeled APPLES AND ORANGES must contain all apples, and therefore the basket labeled ORANGES can only contain the mixture, and the basket labeled APPLES must contain all oranges.


But if it is an orange, you know that the basket labeled APPLES AND ORANGES must contain all oranges, and therefore the basket labeled APPLES can only contain the mixture, and the basket labeled ORANGES must contain all apples.
