This is a badly worded question. The answer is 11 as you have to remove the ten "other" flavours to be sure that the 11th one removed is the one you want. However, there are three ways of answering. The 1st is the one I gave, where you are assured that the 11th one removed is licorice. However, if you asnwered 10, you're also right, as it asked how many had to be removed "before" you were assured. That means that you have to remove 10 and then you will be assured that the next one will be a licorice. However, a third way of interpreting the question gives no possible answer as they are asking how many you must remove before you are certain that the next one will be licorice. You can never be certain that the next one will be licorice unless, by luck, you remove 14 and only 4 of those are licorice.
Does that all make sense?
