Use the $set operator together with the $ positional operator in your update to set elements in array without explicitly specifying the position of the element in the array i.e. 

db.collection.update(
    { "question": "let me go?", "choices.text": "y" }, 
    { $set: { "choices.$.text": "no" } }
);
